Images

Matrix images

go-ci-stable

• built from the latest version of the current stable golang image.
• used for building and testing Go applications, both directly and via Makefile builds.
• intended for use in a build/test matrix of prior, current and upcoming Go releases
• ✔️ provides multiple linters
• ✔️ provides testing tools
• ❌ does not include custom build tools

go-ci-oldstable

• built from the latest version of the current outgoing stable golang image.
• used for building and testing Go applications, both directly and via Makefile builds.
• intended for use in a build/test matrix of prior, current and upcoming Go releases
• ✔️ provides multiple linters
• ✔️ provides testing tools
• ❌ does not include custom build tools

go-ci-unstable

• built from the latest available non-stable golang:beta image, golang:rc image or if not recently available, the latest stable golang image
  • intended to test whether new Go versions break existing code or surface problems in existing code that current Go releases do not
• used for building and testing Go applications, both directly and via Makefile builds

Mirror build images

go-ci-mirror-build-*

• built from the latest version of the golang image for that series
  • e.g., the go-ci-mirror-build-go1.14 image is built from the final release version in the 1.14 series (1.14.15)
• intended to mirror the upstream golang image for Makefile-driven testing, linting and build tasks.
• few (if any) customizations are intended for this image, instead relying on a project's Makefile or other build tool to setup the environment for tasks such as testing, linting & building source code
• ❌ does not include linters
• ❌ does not include testing tools
• ❌ does not include custom build tools

These images are intended to assist with asserting that projects build with the latest version in a specific series.

go-ci-oldstable-mirror-build

Unlike most other images, the go-ci-oldstable-mirror-build name is not the title of an image (such as go-ci-stable), but rather an additional tag for the latest version of the golang image for the oldstable series.

---

• built from the latest version of the golang image for the oldstable series
  • e.g., if the latest oldstable version of the Go toolchain is 1.19.6 and 1.20.1 is the latest in the stable series, the go-ci-oldstable-mirror-build image will refer to the 1.19.6 image
• intended to mirror the latest oldstable (outgoing) upstream golang image for Makefile-driven testing, linting and build tasks.
• few (if any) customizations are intended for this image, instead relying on a project's Makefile or other build tool to setup the environment for tasks such as testing, linting & building source code
• ❌ does not include linters
• ❌ does not include testing tools
• ❌ does not include custom build tools

These images are intended to assist with asserting that projects build with the latest version in the outgoing stable (aka, oldstable) series.

go-ci-stable-mirror-build

Unlike most other images, the go-ci-stable-mirror-build name is not the title of an image (such as go-ci-stable), but rather an additional tag for the latest version of the golang image for the stable series.

---

• built from the latest version of the golang image for the current stable series
  • e.g., if the latest oldstable version of the Go toolchain is 1.19.6 and 1.20.1 is the latest in the stable series, the go-ci-stable-mirror-build image tag will refer to the 1.20.1 image
• intended to mirror the latest stable (current) upstream golang image for Makefile-driven testing, linting and build tasks.
• few (if any) customizations are intended for this image, instead relying on a project's Makefile or other build tool to setup the environment for tasks such as testing, linting & building source code
• ❌ does not include linters
• ❌ does not include testing tools
• ❌ does not include custom build tools

These images are intended to assist with asserting that projects build with the latest version in the current stable series.
