sdrangel/swagger/docker

Running Swagger code generation in Docker containers

The server folder contains files to build the http server image used to serve the files referenced in the $ref field of Swagger .yaml files.

The codegen folder contains files to build the code generator swagger-codegen used to generate the source and documentary files used to support SDRangel REST API.

The compose folder contains files to build the Docker compose stack comprising the server and codegen containers.

The SDRangel source tree is mounted in both containers as writable so the generated code can be written directly from the code generator or the Swagger files served by the http server.

Install Docker on Ubuntu

sudo apt install docker.io docker-buildx docker-compose
sudo usermod -aG docker $USER
sudo reboot

Server

Use build.sh to build the image. It takes the following arguments:

• -t: Image tag name latest is the default. The image is sdrangel/swagger/server:<tag>
• -f: Specify a Dockerfile (default is Dockerfile in current directory i.e. '.')

The run.sh script is used to run the image on its own and is used for development only

Codegen

Use build.sh to build the image. It takes the following arguments:

• -b: Git repository branch name (default sdrangel)
• -c: Arbitrary clone label. Clone again if different from the last label (default current timestamp)
• -t: Docker image tag. Use git tag or commit hash (default latest)
• -f: Specify a Dockerfile (default is Dockerfile in current directory i.e. '.')

Compose

Use run.sh to create or delete the Docker compose stack. It takes the following arguments:

• -D: Use this option to bring down the compose stack (default is to bring up).
• -t: Docker codegen image tag (default latest)
• -T: Docker server image tag (default latest)
• -b: SDRangel source code root path (default /opt/build/sdrangel)
• -c: Compose stack name (default sdrangelswg)

The stack is composed of two containers sharing the 172.20.0.0/16 network internally.

• sdrangel_swgserver: The http server that listens on port 8081 serving files in /opt/build/sdrangel/swagger/sdrangel
• sdrangel_swgcodegen: The container with the Swagger code generator. The working directory is /opt/build/sdrangel/swagger/sdrangel.

Use login.sh to start a shell in the sdrangel_swgcodegen container. At the prompt run generate.sh to generate the code from the Swagger definition files.
