fig.yml reference
|
|
=================
|
|
|
|
Each service defined in `fig.yml` must specify exactly one of `image` or `build`. Other keys are optional, and are analogous to their `docker run` command-line counterparts.
|
|
|
|
As with `docker run`, options specified in the Dockerfile (e.g. `CMD`, `EXPOSE`, `VOLUME`, `ENV`) are respected by default - you don't need to specify them again in `fig.yml`.
|
|
|
|
```yaml
|
|
-- Tag or partial image ID. Can be local or remote - Fig will attempt to pull
|
|
-- if it doesn't exist locally.
|
|
image: ubuntu
|
|
image: orchardup/postgresql
|
|
image: a4bc65fd
|
|
|
|
-- Path to a directory containing a Dockerfile. Fig will build and tag it with
|
|
-- a generated name, and use that image thereafter.
|
|
build: /path/to/build/dir
|
|
|
|
-- Override the default command.
|
|
command: bundle exec thin -p 3000
|
|
|
|
-- Link to containers in another service. Optionally specify an alternate name
|
|
-- for the link, which will determine how environment variables are prefixed,
|
|
-- e.g. "db" -> DB_1_PORT, "db:database" -> DATABASE_1_PORT
|
|
links:
|
|
- db
|
|
- db:database
|
|
- redis
|
|
|
|
-- Expose ports. Either specify both ports (HOST:CONTAINER), or just the
|
|
-- container port (a random host port will be chosen).
|
|
-- Note: When mapping ports in the HOST:CONTAINER format, you may experience
|
|
-- erroneous results when using a container port lower than 60, because YAML
|
|
-- will parse numbers in the format "xx:yy" as sexagesimal (base 60). For
|
|
-- this reason, we recommend always explicitly specifying your port mappings
|
|
-- as strings.
|
|
ports:
|
|
- "3000"
|
|
- "8000:8000"
|
|
- "49100:22"
|
|
|
|
-- Map volumes from the host machine (HOST:CONTAINER).
|
|
volumes:
|
|
- cache/:/tmp/cache
|
|
|
|
-- Add environment variables.
|
|
environment:
|
|
RACK_ENV: development
|
|
```
