FeG Docker Setup

The FeG runs each service in its own Docker container. Production services are defined in docker-compose.yml. Development services are defined in docker-compose.override.yml. The development test service is used to run unit tests and regenerate Swagger/Protobuf code. The development test service can also be used to perform other development-related procedures.

Requirements​

To run the FeG with docker, both docker and docker compose must be installed.

NOTE: If you are running the FeG on Mac, you will need to increase the memory limit of the docker daemon to at least 4GB to build the images. Otherwise, when building the Go image, you may see an error message similar to this: /usr/local/go/pkg/tool/linux_amd64/link: signal: killed.

The rootCA.pem certificate must be located in the .cache/test_certs folder, so that it can be mounted into the appropriate containers from there.

Development​

Follow these steps to run the FeG services:

  1. cd magma/feg/gateway/docker
  2. docker-compose build
  3. docker-compose up -d

Each service should now be running in each of its containers. By default, both production and development services should be running. To place a shell into the test container, run the command:

docker-compose exec test /bin/bash

The test container contains the mounted source code and configuration settings. The mounted source code and configuration settings can be changed externally and the changes will be reflected inside the test container. Run the command make precommit in the container before submitting a patch.

To make changes to currently running FeG services, the containers must be rebuilt and restarted:

  1. docker-compose down
  2. docker-compose build
  3. docker-compose up -d

To manage the containers, the following commands are useful:

  • docker-compose ps (get status of each container)
  • docker-compose logs -f (tail logs of all containers)
  • docker-compose logs -f <service name> (tail logs of a particular service)
  • docker-compose down (stop all services)

Publishing the images​

To push production images to a private docker registry, use the following script:

[/magma/feg/gateway/docker]$ ../../../orc8r/tools/docker/publish.sh -r <REGISTRY> -i gateway_python
[/magma/feg/gateway/docker]$ ../../../orc8r/tools/docker/publish.sh -r <REGISTRY> -i gateway_go
