I have a Phoenix app that I am deploy to Kuberenetes. My deploy script was working fine then all of a sudden it started erroring out asking for python. I tried adding adp add python but that did not help. I am using bitwalker/alpine-elixir:latest and bitwalker/alpine-erlang-base:latest. My error is $ apk add --update make ca-certificates openssl python fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/main/x86_64/APKINDEX.tar.gz fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/community/x86_64/APKINDEX.tar.gz ERROR: unsatisfiable constraints: python (missing): required by: world[python] ERROR: Job failed: exit code 1

My gitlab-ci.yaml file looks like this

and my dockerfile looks like this

#Set environment variables and expose port
EXPOSE 4000

COPY export/ .

CMD ["/opt/app/bin/order_management_portal", "foreground"]

Any help would be greatly appreciated!
