Docker CE¶

Overview¶

Docker CE is an open-source containerization technology for building and containerizing your applications.

Deployment¶

Saltbox dependency.

sb install docker

Usage¶

docker

Role Defaults¶

Variables can be customized using the Inventory. (1)

Example override
```
docker_dns: ["item1", "item2"]
```
Avoid overriding variables ending in _default

When overriding variables that end in _default (like docker_docker_envs_default), you replace the entire default configuration. Future updates that add new default values will not be applied to your setup, potentially breaking functionality.

Instead, use the corresponding _custom variable (like docker_docker_envs_custom) to add your changes. Custom values are merged with defaults, ensuring you receive updates.
