kaniko_envsubst

docker pull papko26/kaniko_envsubst

TLDR:

GoogleContainerTools/kaniko + a8m/envsubst image for gitlab runner on kubernetes.

Why?

Because you may want to use kaniko to build your images in kubernetes, and envsubst to dynamically replace variables in dockerfile from ENV

How?

.gitlab-ci.yml

build_image:
  stage: build
  image:
    name: papko26/kaniko_envsubst
    entrypoint: [""]
  script:
    - cat $CI_PROJECT_NAME.Dockerfile | envsubst > $CI_PROJECT_NAME.busted.Dockerfile
    - echo "{\"auths\":{\"$CI_REGISTRY\":{\"username\":\"$CI_REGISTRY_USER\",\"password\":\"$CI_REGISTRY_PASSWORD\"}}}" > /kaniko/.docker/config.json
    - /kaniko/executor -c . -f $CI_PROJECT_NAME.busted.Dockerfile -d $CI_REGISTRY_IMAGE/base:$CI_COMMIT_TAG -d $CI_REGISTRY_IMAGE/base:latest
