CLI reference
|
|
=============
|
|
|
|
Most commands are run against one or more services. If the service is omitted, it will apply to all services.
|
|
|
|
Run `fig [COMMAND] --help` for full usage.
|
|
|
|
## Options
|
|
|
|
### --verbose
|
|
|
|
Show more output
|
|
|
|
### --version
|
|
|
|
Print version and exit
|
|
|
|
### -f, --file FILE
|
|
|
|
Specify an alternate fig file (default: fig.yml)
|
|
|
|
### -p, --project-name NAME
|
|
|
|
Specify an alternate project name (default: directory name)
|
|
|
|
## Commands
|
|
|
|
### build
|
|
|
|
Build or rebuild services.
|
|
|
|
Services are built once and then tagged as `project_service`, e.g. `figtest_db`. If you change a service's `Dockerfile` or the contents of its build directory, you can run `fig build` to rebuild it.
|
|
|
|
### help
|
|
|
|
Get help on a command.
|
|
|
|
### kill
|
|
|
|
Force stop running containers by sending a `SIGKILL` signal. Optionally the signal can be passed, for example:
|
|
|
|
$ fig kill -s SIGINT
|
|
|
|
### logs
|
|
|
|
View output from services.
|
|
|
|
### port
|
|
|
|
Print the public port for a port binding
|
|
|
|
### ps
|
|
|
|
List containers.
|
|
|
|
### pull
|
|
|
|
Pulls service images.
|
|
|
|
### rm
|
|
|
|
Remove stopped service containers.
|
|
|
|
|
|
### run
|
|
|
|
Run a one-off command on a service.
|
|
|
|
For example:
|
|
|
|
$ fig run web python manage.py shell
|
|
|
|
By default, linked services will be started, unless they are already running.
|
|
|
|
One-off commands are started in new containers with the same config as a normal container for that service, so volumes, links, etc will all be created as expected. The only thing different to a normal container is the command will be overridden with the one specified and by default no ports will be created in case they collide.
|
|
|
|
Links are also created between one-off commands and the other containers for that service so you can do stuff like this:
|
|
|
|
$ fig run db psql -h db -U docker
|
|
|
|
If you do not want linked containers to be started when running the one-off command, specify the `--no-deps` flag:
|
|
|
|
$ fig run --no-deps web python manage.py shell
|
|
|
|
If you want the service's ports to be created and mapped to the host, specify the `--service-ports` flag:
|
|
$ fig run --service-ports web python manage.py shell
|
|
|
|
### scale
|
|
|
|
Set number of containers to run for a service.
|
|
|
|
Numbers are specified in the form `service=num` as arguments.
|
|
For example:
|
|
|
|
$ fig scale web=2 worker=3
|
|
|
|
### start
|
|
|
|
Start existing containers for a service.
|
|
|
|
### stop
|
|
|
|
Stop running containers without removing them. They can be started again with `fig start`.
|
|
|
|
### up
|
|
|
|
Build, (re)create, start and attach to containers for a service.
|
|
|
|
Linked services will be started, unless they are already running.
|
|
|
|
By default, `fig up` will aggregate the output of each container, and when it exits, all containers will be stopped. If you run `fig up -d`, it'll start the containers in the background and leave them running.
|
|
|
|
By default if there are existing containers for a service, `fig up` will stop and recreate them (preserving mounted volumes with [volumes-from]), so that changes in `fig.yml` are picked up. If you do no want containers to be stopped and recreated, use `fig up --no-recreate`. This will still start any stopped containers, if needed.

## Environment Variables
|
|
|
|
Several environment variables can be used to configure Fig's behaviour.
|
|
|
|
Variables starting with `DOCKER_` are the same as those used to configure the Docker command-line client. If you're using boot2docker, `$(boot2docker shellinit)` will set them to their correct values.
|
|
|
|
### FIG\_PROJECT\_NAME
|
|
|
|
Set the project name, which is prepended to the name of every container started by Fig. Defaults to the `basename` of the current working directory.
|
|
|
|
### FIG\_FILE
|
|
|
|
Set the path to the `fig.yml` to use. Defaults to `fig.yml` in the current working directory.
|
|
|
|
### DOCKER\_HOST
|
|
|
|
Set the URL to the docker daemon. Defaults to `unix:///var/run/docker.sock`, as with the docker client.
|
|
|
|
### DOCKER\_TLS\_VERIFY
|
|
|
|
When set to anything other than an empty string, enables TLS communication with the daemon.
|
|
|
|
### DOCKER\_CERT\_PATH
|
|
|
|
Configure the path to the `ca.pem`, `cert.pem` and `key.pem` files used for TLS verification. Defaults to `~/.docker`.
