How to use Bitbucket Pipelines to build a Go (golang) project

Stepping through bitbucket-pipelines.yml

Setup the environment

A general-purpose setup script is used to setup the environment.

source bitbucket-pipelines-go.sh

The setup script sets the IMPORT_PATH environment variable. An import path is a string that uniquely identifies a package. The import path for this example project is built on two of Bitbucket Pipelines default environment variables.

The setup script creates a package directory inside the Go workspace. We are using the latest tag of the official golang docker image. This image uses the /go directory as its Go workspace (and sets the GOPATH environment variable).

The setup script links the working directory to the package directory. Bitbucket Pipelines overrides the working directory of the golang Docker image. We can rely on the fact that the working directory contains our project's source code, and add a symbolic link from the Go workspace to the current working directory. This allows us to build and install the program with the go tool.

Compile and test stringutil library

Our very simple stringutil library has a dependency on xstrings. The go get command is used to download this dependency.

cd ${IMPORT_PATH}/stringutil
go get

Next this project's stringutil library is compiled with go build.

go build

Finally, the go test command runs stringutil/reverse_test.go.

go test

Install and run the hello program

The hello program depends on the stringutil library. The go install command compiles it and places the binary in ${GOPATH}/bin. The golang Docker image has ${GOPATH}/bin on its ${PATH}.

cd ${IMPORT_PATH}/hello
go install 
hello
