# Docker Compose App Role
|
||||
# patrickj.docker_compose_app
|
||||
|
||||
A flexible Ansible role for deploying and managing Docker Compose applications with features including backup/restore and healthchecks.
|
||||
Ansible collection providing a single reusable role for deploying and managing Docker Compose applications.
|
||||
|
||||
## Overview
|
||||
## Contents
|
||||
|
||||
This role provides a standardized way to deploy containerized applications using Docker Compose. It handles directory creation, template rendering, and container lifecycle management.
|
||||
- `patrickj.docker_compose_app.app` — the base role. See [`roles/app/README.md`](roles/app/README.md) for usage, variables, and examples.
|
||||
|
||||
## Features
|
||||
|
||||
- **Template-based deployment** with Jinja2 templating
|
||||
- **Dual backup system** (controller + remote host)
|
||||
- **Health checks** and deployment verification
|
||||
- **Multiple deployment modes** (template, file, or inline content)
|
||||
- **Flexible directory management**
|
||||
- **Configurable backup retention policies**
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Create a New Role
|
||||
|
||||
Use the provided script to create a new application skeleton role:
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
./create_app_role.sh my-app
|
||||
ansible-galaxy collection install git+https://git.jaroszew.ski/ansible/ansible-collection-docker-compose-app.git
|
||||
```
|
||||
|
||||
This creates:
|
||||
```
|
||||
roles/my-app/
|
||||
├── defaults/main.yml # Default variables
|
||||
├── meta/main.yml # Role metadata and dependencies
|
||||
└── templates/
|
||||
└── compose.yml.j2 # Docker Compose template
|
||||
```
|
||||
|
||||
### 2. Configure Your Application
|
||||
|
||||
Edit `roles/my-app/defaults/main.yml`:
|
||||
Or as a dependency in another collection's `galaxy.yml`:
|
||||
|
||||
```yaml
|
||||
---
|
||||
app_role_name: my-app
|
||||
|
||||
my_app_container_name: "{{ app_name | default('my-app') }}"
|
||||
my_app_container_version: latest
|
||||
my_app_restart_policy: "{{ app_restart_policy }}"
|
||||
my_app_http_port: 8080
|
||||
my_app_data_path: "{{ app_dir }}/data"
|
||||
my_app_config_path: "{{ app_dir }}/config"
|
||||
|
||||
# Optional: directories to create
|
||||
app_subdirectories:
|
||||
- "{{ my_app_data_path }}"
|
||||
- "{{ my_app_config_path }}"
|
||||
|
||||
# Optional: backup configuration
|
||||
app_backup_subdirectories:
|
||||
- "{{ my_app_data_path }}"
|
||||
- "{{ my_app_config_path }}"
|
||||
```
|
||||
|
||||
### 3. Create Docker Compose Template
|
||||
|
||||
Edit `roles/my-app/templates/compose.yml.j2`:
|
||||
|
||||
```yaml
|
||||
---
|
||||
services:
|
||||
my-app:
|
||||
image: "my-app:{{ my_app_container_version }}"
|
||||
container_name: "{{ my_app_container_name }}"
|
||||
restart: "{{ my_app_restart_policy }}"
|
||||
ports:
|
||||
- "{{ my_app_http_port }}:8080"
|
||||
volumes:
|
||||
- "{{ my_app_data_path }}:/data"
|
||||
- "{{ my_app_config_path }}:/config"
|
||||
environment:
|
||||
- TZ={{ app_timezone | default('UTC') }}
|
||||
```
|
||||
|
||||
### 4. Deploy Your Application
|
||||
|
||||
Add to your playbook:
|
||||
|
||||
```yaml
|
||||
---
|
||||
- name: Deploy my application
|
||||
hosts: localhost
|
||||
roles:
|
||||
- role: my-app
|
||||
```
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Backup and Restore
|
||||
|
||||
#### Create a New Backup
|
||||
|
||||
Create an on-demand backup using tags:
|
||||
|
||||
```bash
|
||||
# Backup a specific application
|
||||
ansible-playbook --tags backup playbook.yml
|
||||
```
|
||||
|
||||
Configure backup retention and options in your role's meta vars:
|
||||
|
||||
```yaml
|
||||
# In roles/my-app/meta/main.yml
|
||||
dependencies:
|
||||
- role: patrickj.docker_apps.docker_compose_app
|
||||
vars:
|
||||
app_backup_subdirectories:
|
||||
- "{{ my_app_data_path }}"
|
||||
- "{{ my_app_config_path }}"
|
||||
app_backup_retention_days_controller: 90 # Keep backups for 90 days
|
||||
app_backup_retention_days_remote: 7 # Keep remote backups for 7 days
|
||||
app_backup_stop_services: true # Stop containers during backup
|
||||
"patrickj.docker_compose_app": ">=1.0.0"
|
||||
```
|
||||
|
||||
#### Automated Backups
|
||||
## Scaffolding a new consuming role
|
||||
|
||||
For scheduled backups:
|
||||
`create_app_role.sh` at the repo root scaffolds a new "shim" role that depends on `patrickj.docker_compose_app.app`. Run it from the `roles/` directory of your consuming collection or playbook:
|
||||
|
||||
```bash
|
||||
# Run daily backup at 2 AM - only runs backup tasks
|
||||
0 2 * * * ansible-playbook -i inventory --tags backup my-playbook.yml
|
||||
cd path/to/your/collection/roles
|
||||
/path/to/this/repo/create_app_role.sh my-app
|
||||
```
|
||||
|
||||
### Tag-Based Execution
|
||||
|
||||
The role supports selective execution using tags:
|
||||
|
||||
```bash
|
||||
# Setup only - doesn't start the containers
|
||||
ansible-playbook --tags setup playbook.yml
|
||||
|
||||
# Full deployment - setup + start containers
|
||||
ansible-playbook --tags deploy playbook.yml
|
||||
|
||||
# Restore and deploy
|
||||
ansible-playbook --tags restore,deploy playbook.yml
|
||||
|
||||
# Backup only
|
||||
ansible-playbook --tags backup playbook.yml
|
||||
|
||||
# Update only
|
||||
ansible-playbook --tags update playbook.yml
|
||||
|
||||
# Backup then update
|
||||
ansible-playbook --tags backup,update playbook.yml
|
||||
```
|
||||
|
||||
#### Restore from Backup
|
||||
|
||||
Restore from the latest backup:
|
||||
|
||||
```bash
|
||||
# Setup directories, restore from backup, then deploy
|
||||
ansible-playbook --tags setup,restore,deploy playbook.yml
|
||||
```
|
||||
|
||||
Configure restore options in your role's meta vars:
|
||||
|
||||
```yaml
|
||||
# In roles/my-app/meta/main.yml
|
||||
dependencies:
|
||||
- role: patrickj.docker_apps.docker_compose_app
|
||||
vars:
|
||||
app_restore_source: controller # or 'remote'
|
||||
app_restore_max_age_days: 30 # Only restore backups newer than 30 days
|
||||
```
|
||||
|
||||
Restore from a specific archive by setting the variable at runtime:
|
||||
|
||||
```bash
|
||||
ansible-playbook --tags restore playbook.yml \
|
||||
-e app_restore_archive=/path/to/specific/backup-20240315-120000.tar.gz
|
||||
```
|
||||
|
||||
### Health Checks
|
||||
|
||||
Configure health monitoring:
|
||||
|
||||
```yaml
|
||||
- role: my-app
|
||||
vars:
|
||||
app_name: my-app
|
||||
app_health_check: true
|
||||
app_health_check_method: http
|
||||
app_health_check_url: "http://localhost:8080/health"
|
||||
app_health_check_retries: 30
|
||||
app_health_check_delay: 10
|
||||
```
|
||||
|
||||
### Updates
|
||||
|
||||
Update application containers using tags:
|
||||
|
||||
```bash
|
||||
# Update a specific application
|
||||
ansible-playbook --tags update playbook.yml
|
||||
|
||||
# Update all applications in a playbook
|
||||
ansible-playbook --tags update site.yml
|
||||
```
|
||||
|
||||
**Update process:**
|
||||
1. Stops the application
|
||||
2. Pulls images according to `app_compose_pull` (defaults to `policy`; set to `always` to force fresh pulls)
|
||||
3. Recreates containers with new images
|
||||
4. Runs health checks (if enabled)
|
||||
|
||||
|
||||
### Rollbacks
|
||||
|
||||
Rollback using the restore functionality:
|
||||
|
||||
```bash
|
||||
# First, create a backup then update
|
||||
ansible-playbook --tags backup,update playbook.yml
|
||||
|
||||
# If update fails, rollback from backup
|
||||
ansible-playbook --tags restore playbook.yml
|
||||
```
|
||||
|
||||
**Important Notes:**
|
||||
- Updates do NOT create automatic backups - create backups manually beforehand
|
||||
- Rollbacks must be triggered manually using the restore functionality
|
||||
- Using `latest` tags prevents effective rollbacks since the old image is overwritten
|
||||
- For production, use specific version tags instead of `latest`
|
||||
|
||||
|
||||
### Multiple Instances
|
||||
|
||||
Deploy multiple instances of the same application:
|
||||
|
||||
```yaml
|
||||
- role: jellyfin
|
||||
vars:
|
||||
app_name: jellyfin-movies
|
||||
jellyfin_http_port: 8096
|
||||
|
||||
- role: jellyfin
|
||||
vars:
|
||||
app_name: jellyfin-tv
|
||||
jellyfin_http_port: 8097
|
||||
```
|
||||
|
||||
|
||||
### Custom Templates and Files
|
||||
|
||||
#### Override template location:
|
||||
|
||||
```yaml
|
||||
- role: my-app
|
||||
vars:
|
||||
app_compose_template: /path/to/custom/compose.yml.j2
|
||||
```
|
||||
|
||||
#### Use a static compose file:
|
||||
|
||||
If you have an existing `docker-compose.yml` file that doesn't need templating:
|
||||
|
||||
```yaml
|
||||
- role: my-app
|
||||
vars:
|
||||
app_name: my-app
|
||||
app_compose_file: /path/to/existing/docker-compose.yml
|
||||
```
|
||||
|
||||
The file will be copied as-is to the application directory without Jinja2 processing.
|
||||
|
||||
#### Use inline content:
|
||||
|
||||
```yaml
|
||||
- role: patrickj.docker_apps.docker_compose_app
|
||||
vars:
|
||||
app_name: simple-app
|
||||
app_role_name: simple-app
|
||||
app_compose_content: |
|
||||
services:
|
||||
app:
|
||||
image: nginx:alpine
|
||||
ports:
|
||||
- "80:80"
|
||||
```
|
||||
|
||||
## Configuration Reference
|
||||
|
||||
### Required Externals
|
||||
|
||||
These variables have no defaults and must be set by the calling playbook (typically as group_vars or host_vars). They are consumed by the defaults shown further down; if you override every derived variable that uses them, you can leave the corresponding external unset.
|
||||
|
||||
| Variable | Description | Consumed by |

- src: config.json.j2
|
||||
dest: "{{ app_dir }}/config/app.json"
|
||||
- src: env.j2
|
||||
dest: "{{ app_dir }}/.env"
|
||||
```
|
||||
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use semantic versioning** for container tags instead of `latest`
|
||||
2. **Test restore procedures** regularly to ensure backups are valid
|
||||
3. **Use specific directories** for backups instead of entire app directory
|
||||
4. **Monitor disk usage** on backup storage locations
|
||||
|
||||
## Architecture
|
||||
|
||||
The role is organized into logical task files for selective execution:
|
||||
|
||||
```
|
||||
├── setup.yml # Validation, directories, and templates
|
||||
├── restore.yml # Backup restoration logic
|
||||
├── deploy.yml # Docker Compose deployment and startup
|
||||
├── health_check.yml # Health monitoring and verification
|
||||
├── backup.yml # Backup creation and management
|
||||
├── update.yml # Container update and image pulling
|
||||
└── manage_compose.yml # Docker Compose lifecycle management
|
||||
```
|
||||
|
||||
### Task Execution Flow
|
||||
|
||||
1. **Setup** (`setup.yml`) - [setup, deploy]
|
||||
- Docker/Compose validation
|
||||
- Variable validation and security checks
|
||||
- Directory creation
|
||||
- Additional template deployment
|
||||
|
||||
2. **Restore** (`restore.yml`) - [restore, never]
|
||||
- Backup file selection and validation
|
||||
- Service stopping
|
||||
- Archive extraction
|
||||
- Service restart
|
||||
|
||||
3. **Deploy** (`deploy.yml`) - [deploy]
|
||||
- Docker Compose file creation
|
||||
- Container startup and management
|
||||
|
||||
4. **Health Check** (`health_check.yml`) - [deploy, healthcheck]
|
||||
- Service health verification
|
||||
- Endpoint monitoring
|
||||
|
||||
5. **Backup** (`backup.yml`) - [backup, never]
|
||||
- Service stopping (optional)
|
||||
- Archive creation
|
||||
- Backup copying and cleanup
|
||||
- Service restart
|
||||
|
||||
6. **Update** (`update.yml`) - [update, never]
|
||||
- Service stopping
|
||||
- Image pulling
|
||||
- Container recreation
|
||||
- Health verification
|
||||
|
||||
Each task file is designed to be idempotent and can be run multiple times safely.

# Docker Compose App Role
|
||||
|
||||
A flexible Ansible role for deploying and managing Docker Compose applications with features including backup/restore and healthchecks.
|
||||
|
||||
## Overview
|
||||
|
||||
This role provides a standardized way to deploy containerized applications using Docker Compose. It handles directory creation, template rendering, and container lifecycle management.
|
||||
|
||||
## Requirements
|
||||
|
||||
- Collections: `community.docker` (>=1.10.0) and `ansible.posix` (>=1.4.0). Both are declared as collection dependencies and installed automatically with the collection.
|
||||
- The backup workflow copies archives to the controller with `ansible.posix.synchronize`, so **`rsync` must be installed on both the controller and the managed host**.
|
||||
|
||||
## Features
|
||||
|
||||
- **Template-based deployment** with Jinja2 templating
|
||||
- **Dual backup system** (controller + remote host)
|
||||
- **Health checks** and deployment verification
|
||||
- **Multiple deployment modes** (template, file, or inline content)
|
||||
- **Flexible directory management**
|
||||
- **Configurable backup retention policies**
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Create a New Role
|
||||
|
||||
Use the provided script to create a new application skeleton role:
|
||||
|
||||
```bash
|
||||
./create_app_role.sh my-app
|
||||
```
|
||||
|
||||
This creates:
|
||||
```
|
||||
roles/my-app/
|
||||
├── defaults/main.yml # Default variables
|
||||
├── meta/main.yml # Role metadata and dependencies
|
||||
└── templates/
|
||||
└── compose.yml.j2 # Docker Compose template
|
||||
```
|
||||
|
||||
### 2. Configure Your Application
|
||||
|
||||
Edit `roles/my-app/defaults/main.yml`:
|
||||
|
||||
```yaml
|
||||
---
|
||||
app_role_name: my-app
|
||||
|
||||
my_app_container_name: "{{ app_name | default('my-app') }}"
|
||||
my_app_container_version: latest
|
||||
my_app_restart_policy: "{{ app_restart_policy }}"
|
||||
my_app_http_port: 8080
|
||||
my_app_data_path: "{{ app_dir }}/data"
|
||||
my_app_config_path: "{{ app_dir }}/config"
|
||||
|
||||
# Optional: directories to create
|
||||
app_subdirectories:
|
||||
- "{{ my_app_data_path }}"
|
||||
- "{{ my_app_config_path }}"
|
||||
|
||||
# Optional: backup configuration
|
||||
app_backup_subdirectories:
|
||||
- "{{ my_app_data_path }}"
|
||||
- "{{ my_app_config_path }}"
|
||||
```
|
||||
|
||||
### 3. Create Docker Compose Template
|
||||
|
||||
Edit `roles/my-app/templates/compose.yml.j2`:
|
||||
|
||||
```yaml
|
||||
---
|
||||
services:
|
||||
my-app:
|
||||
image: "my-app:{{ my_app_container_version }}"
|
||||
container_name: "{{ my_app_container_name }}"
|
||||
restart: "{{ my_app_restart_policy }}"
|
||||
ports:
|
||||
- "{{ my_app_http_port }}:8080"
|
||||
volumes:
|
||||
- "{{ my_app_data_path }}:/data"
|
||||
- "{{ my_app_config_path }}:/config"
|
||||
environment:
|
||||
- TZ={{ app_timezone | default('UTC') }}
|
||||
```
|
||||
|
||||
### 4. Deploy Your Application
|
||||
|
||||
Add to your playbook:
|
||||
|
||||
```yaml
|
||||
---
|
||||
- name: Deploy my application
|
||||
hosts: localhost
|
||||
roles:
|
||||
- role: my-app
|
||||
```
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Backup and Restore
|
||||
|
||||
#### Create a New Backup
|
||||
|
||||
Create an on-demand backup using tags:
|
||||
|
||||
```bash
|
||||
# Backup a specific application
|
||||
ansible-playbook --tags backup playbook.yml
|
||||
```
|
||||
|
||||
Configure backup retention and options in your role's meta vars:
|
||||
|
||||
```yaml
|
||||
# In roles/my-app/meta/main.yml
|
||||
dependencies:
|
||||
- role: patrickj.docker_apps.docker_compose_app
|
||||
vars:
|
||||
app_backup_subdirectories:
|
||||
- "{{ my_app_data_path }}"
|
||||
- "{{ my_app_config_path }}"
|
||||
app_backup_retention_days_controller: 90 # Keep backups for 90 days
|
||||
app_backup_retention_days_remote: 7 # Keep remote backups for 7 days
|
||||
app_backup_stop_services: true # Stop containers during backup
|
||||
```
|
||||
|
||||
When `app_backup_stop_services` is enabled the containers are stopped only while the tarball is created on the managed host, then restarted immediately — the transfer of the archive back to the controller (via rsync) happens after the application is running again, so downtime is limited to the snapshot itself.
|
||||
|
||||
#### Automated Backups
|
||||
|
||||
For scheduled backups:
|
||||
|
||||
```bash
|
||||
# Run daily backup at 2 AM - only runs backup tasks
|
||||
0 2 * * * ansible-playbook -i inventory --tags backup my-playbook.yml
|
||||
```
|
||||
|
||||
### Tag-Based Execution
|
||||
|
||||
The role supports selective execution using tags:
|
||||
|
||||
```bash
|
||||
# Setup only - creates directories and renders the compose file, but doesn't start the containers
|
||||
ansible-playbook --tags setup playbook.yml
|
||||
|
||||
# Full deployment - setup + start containers
|
||||
ansible-playbook --tags deploy playbook.yml
|
||||
|
||||
# Restore and deploy
|
||||
ansible-playbook --tags restore,deploy playbook.yml
|
||||
|
||||
# Backup only
|
||||
ansible-playbook --tags backup playbook.yml
|
||||
|
||||
# Update only
|
||||
ansible-playbook --tags update playbook.yml
|
||||
|
||||
# Backup then update
|
||||
ansible-playbook --tags backup,update playbook.yml
|
||||
```
|
||||
|
||||
#### Restore from Backup
|
||||
|
||||
Restore from the latest backup:
|
||||
|
||||
```bash
|
||||
# Setup directories, restore from backup, then deploy
|
||||
ansible-playbook --tags setup,restore,deploy playbook.yml
|
||||
```
|
||||
|
||||
Configure restore options in your role's meta vars:
|
||||
|
||||
```yaml
|
||||
# In roles/my-app/meta/main.yml
|
||||
dependencies:
|
||||
- role: patrickj.docker_apps.docker_compose_app
|
||||
vars:
|
||||
app_restore_source: controller # or 'remote'
|
||||
app_restore_max_age_days: 30 # Only restore backups newer than 30 days
|
||||
```
|
||||
|
||||
Restore from a specific archive by setting the variable at runtime:
|
||||
|
||||
```bash
|
||||
ansible-playbook --tags restore playbook.yml \
|
||||
-e app_restore_archive=/path/to/specific/backup-20240315-120000.tar.gz
|
||||
```
|
||||
|
||||
### Health Checks
|
||||
|
||||
Configure health monitoring:
|
||||
|
||||
```yaml
|
||||
- role: my-app
|
||||
vars:
|
||||
app_name: my-app
|
||||
app_health_check: true
|
||||
app_health_check_method: http
|
||||
app_health_check_url: "http://localhost:8080/health"
|
||||
app_health_check_retries: 30
|
||||
app_health_check_delay: 10
|
||||
```
|
||||
|
||||
### Updates
|
||||
|
||||
Update application containers using tags:
|
||||
|
||||
```bash
|
||||
# Update a specific application
|
||||
ansible-playbook --tags update playbook.yml
|
||||
|
||||
# Update all applications in a playbook
|
||||
ansible-playbook --tags update site.yml
|
||||
```
|
||||
|
||||
**Update process:**
|
||||
1. Stops the application
|
||||
2. Pulls images according to `app_compose_pull` (defaults to `policy`; set to `always` to force fresh pulls)
|
||||
3. Recreates containers with new images
|
||||
4. Runs health checks (if enabled)
|
||||
|
||||
|
||||
### Rollbacks
|
||||
|
||||
Rollback using the restore functionality:
|
||||
|
||||
```bash
|
||||
# First, create a backup then update
|
||||
ansible-playbook --tags backup,update playbook.yml
|
||||
|
||||
# If update fails, rollback from backup
|
||||
ansible-playbook --tags restore playbook.yml
|
||||
```
|
||||
|
||||
**Important Notes:**
|
||||
- Updates do NOT create automatic backups - create backups manually beforehand
|
||||
- Rollbacks must be triggered manually using the restore functionality
|
||||
- Using `latest` tags prevents effective rollbacks since the old image is overwritten
|
||||
- For production, use specific version tags instead of `latest`
|
||||
|
||||
|
||||
### Multiple Instances
|
||||
|
||||
Deploy multiple instances of the same application:
|
||||
|
||||
```yaml
|
||||
- role: jellyfin
|
||||
vars:
|
||||
app_name: jellyfin-movies
|
||||
jellyfin_http_port: 8096
|
||||
|
||||
- role: jellyfin
|
||||
vars:
|
||||
app_name: jellyfin-tv
|
||||
jellyfin_http_port: 8097
|
||||
```
|
||||
|
||||
|
||||
### Custom Templates and Files
|
||||
|
||||
#### Override template location:
|
||||
|
||||
```yaml
|
||||
- role: my-app
|
||||
vars:
|
||||
app_compose_template: /path/to/custom/compose.yml.j2
|
||||
```
|
||||
|
||||
#### Use a static compose file:
|
||||
|
||||
If you have an existing `docker-compose.yml` file that doesn't need templating:
|
||||
|
||||
```yaml
|
||||
- role: my-app
|
||||
vars:
|
||||
app_name: my-app
|
||||
app_compose_file: /path/to/existing/docker-compose.yml
|
||||
```
|
||||
|
||||
The file will be copied as-is to the application directory without Jinja2 processing.
|
||||
|
||||
#### Use inline content:
|
||||
|
||||
```yaml
|
||||
- role: patrickj.docker_apps.docker_compose_app
|
||||
vars:
|
||||
app_name: simple-app
|
||||
app_role_name: simple-app
|
||||
app_compose_content: |
|
||||
services:
|
||||
app:
|
||||
image: nginx:alpine
|
||||
ports:
|
||||
- "80:80"
|
||||
```
|
||||
|
||||
## Configuration Reference
|
||||
|
||||
### Required Externals
|
||||
|
||||
These variables have no defaults and must be set by the calling playbook (typically as group_vars or host_vars). They are consumed by the defaults shown further down; if you override every derived variable that uses them, you can leave the corresponding external unset.
|
||||
|
||||
| Variable | Description | Consumed by |
|
||||
|----------|-------------|-------------|
|
||||
| `host_root_path` | Base directory on the **target host** under which each app's directory is created (e.g. `/srv/apps`, `/opt/docker`) | `app_dir` |
|
||||
| `backup_path` | Base directory on the **controller** where fetched backup archives are stored (e.g. `~/backups`) | `app_backup_path` |
|
||||
|
||||
The `templates/` directory of the calling shim role is discovered automatically via `ansible_parent_role_paths` — no path variable to set.
|
||||
|

|
||||
| `app_compose_recreate` | `auto` | Container recreate strategy |
|
||||
| `app_compose_project_name` | `{{ app_dir \| basename }}` | Compose project name; override when your compose file sets a non-default project name |

||||
```yaml
|
||||
app_extra_templates:
|
||||
- src: config.json.j2
|
||||
dest: "{{ app_dir }}/config/app.json"
|
||||
- src: env.j2
|
||||
dest: "{{ app_dir }}/.env"
|
||||
```
|
||||
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use semantic versioning** for container tags instead of `latest`
|
||||
2. **Test restore procedures** regularly to ensure backups are valid
|
||||
3. **Use specific directories** for backups instead of entire app directory
|
||||
4. **Monitor disk usage** on backup storage locations
|
||||
|
||||
## Architecture
|
||||
|
||||
The role is organized into logical task files for selective execution:
|
||||
|
||||
```
|
||||
├── setup.yml # Validation, directories, and templates
|
||||
├── restore.yml # Backup restoration logic
|
||||
├── deploy.yml # Docker Compose deployment and startup
|
||||
├── health_check.yml # Health monitoring and verification
|
||||
├── backup.yml # Backup creation and management
|
||||
├── update.yml # Container update and image pulling
|
||||
└── manage_compose.yml # Docker Compose lifecycle management
|
||||
```
|
||||
|
||||
### Task Execution Flow
|
||||
|
||||
1. **Setup** (`setup.yml`) - [setup, deploy]
|
||||
- Docker/Compose validation
|
||||
- Variable validation and security checks
|
||||
- Directory creation
|
||||
- Additional template deployment
|
||||
|
||||
2. **Restore** (`restore.yml`) - [restore, never]
|
||||
- Backup file selection and validation
|
||||
- Service stopping
|
||||
- Archive extraction
|
||||
- Service restart
|
||||
|
||||
3. **Deploy** (`deploy.yml`) - [deploy]
|
||||
- Docker Compose file creation
|
||||
- Container startup and management
|
||||
|
||||
4. **Health Check** (`health_check.yml`) - [deploy, healthcheck]
|
||||
- Service health verification
|
||||
- Endpoint monitoring
|
||||
|
||||
5. **Backup** (`backup.yml`) - [backup, never]
|
||||
- Service stopping (optional)
|
||||
- Archive creation
|
||||
- Backup copying and cleanup
|
||||
- Service restart
|
||||
|
||||
6. **Update** (`update.yml`) - [update, never]
|
||||
- Service stopping
|
||||
- Image pulling
|
||||
- Container recreation
|
||||
- Health verification
|
||||
|
||||
Each task file is designed to be idempotent and can be run multiple times safely.
