Setup

Go

Install Go 1.17.x.

Clone the repository:

$ git clone https://github.com/spinnaker/spin

Afterward, use go build to build the program. This will automatically fetch dependencies.

$ go build

Upon first build, you may see output while the go tool fetches dependencies.

To verify dependencies match checksums under go.sum, run go mod verify.

To clean up any old, unused go.mod or go.sum lines, run go mod tidy.

Running Spin

Run using

./spin <cmds> <flags>

Running tests

From the root spin/ directory run:

go test -v ./...

Updating the Gate API

Spin CLI uses Swagger to generate the API client library for Gate.

Spin CLI's master branch should be using Gate's master swagger definition.

Spin CLI's release-{major}-{minor}.x branch should be using Gate's corresponding release-{major}-{minor}.x swagger definition.

To update the client library:

• Use the Swagger Codegen to generate the new library and drop it into the spin project

  # decide branch to update
  branch=release-1.##.x
  
  # check out appropriate Gate branch
  # assuming Gate checked out in same parent directory as spin and up to date
  cd ../gate
  git checkout "$branch"
  
  # generate Gate swagger client library branch
  swagger/generate_swagger.sh
  
  # check out appropriate Spin branch
  cd ../spin
  git checkout "$branch"
  
  # set Swagger Codegen tool version
  SWAGGER_CODEGEN_VERSION=$(cat gateapi/.swagger-codegen/VERSION)
  
  rm -rf gateapi/ \
  && docker run -it \
      -v "$PWD/../gate/swagger/:/tmp/gate" \
      -v "$PWD/gateapi/:/tmp/go/" \
      "swaggerapi/swagger-codegen-cli:${SWAGGER_CODEGEN_VERSION}" generate -i /tmp/gate/swagger.json -l go -o /tmp/go/
  
  # create branch off $branch and PR changes
  git checkout -b "$branch-swagger"
