How-tos

To build a Docker image that has dependencies from private repositories, you should pass the .netrc configuration (see more in How to access private repos in Go). Ideally, this configuration should be passed as a secret: FROM golang:1.22.2-alpine3.19 AS deps COPY go.mod go.sum ./ # Copy secrets from /kaniko for Kaniko or from /run/secrets for Podman/Buddah RUN --mount=type=secret,id=netrc \ cp /kaniko/netrc "$HOME"/.netrc || cp /run/secrets/netrc "$HOME"/.netrc && \ go mod download && \ rm "$HOME"/.netrc GitLab CI/CD In GitLab CI, to build the image, you need to create a .netrc configuration with CI_JOB_TOKEN and pass it to Kaniko secrets. Here is an example: ...

When downloading packages, Go checks the public Go Checksum Database to verify the package checksum. Private Git packages, such as those on a private GitLab instance, aren’t in that database, so downloading them will fail. This can be fixed by setting GOPRIVATE=private.example.com. This instructs Go not to check the Checksum Database for packages in the private.example.com domain. For GitLab, first set up access to repositories: Create a GitLab Access Token with the read_api scope. Update your ${HOME}/.netrc file, and add: machine private.example.com login your.email@example.com password gitlab_access_token More information can be found in the GitLab documentation. ...

Let’s say you have Go 1.20.1 installed locally, but the project you are working on requires Go 1.22.3. First, install the additional version of the Go SDK. VS Code Set GOROOT to point to the Go version you need. Add the following to the workspace settings: "go.goroot": "${env:HOME}/sdk/go1.22.3" GoLand Go to Settings → Go → GOROOT and add or select the version you need there.
