The Daily WTF

A recent code-review on a new build pipeline got Sandra‘s attention (previously). The normally responsible and reliable developer responsible for the commit included this in their Jenkinsfile:

sh ”’ if ! command -v yamllint &> /dev/null; then if command -v apt-get &> /dev/null; then apt-get update && apt-get install -y yamllint elif command -v apk &> /dev/null; then apk add –no-cache yamllint elif command -v pip3 &> /dev/null; then pip3 install –break-system-packages yamllint fi fi find . -name ‘*.yaml’ -exec yamllint {} ; || true find . -name ‘*.yml’ -exec yamllint {} ; || true ”’

So the goal of this script is to check to see if the yamllint command is available. If it isn’t, we check if apt-get is available, and if it is, we use that to install yamllint. Failing that, we try apk, Alpine’s package manager, and failing that we use pip3 to install it
