Decrypt with gpg from inside a docker container

问题

I have an encrypted file with gpg that I want to decrypt from inside a docker container. gpg is not found on the container, how would I add it.

回答1:

Depending on your base image (used by your container), you would need to add to your Dockerfile
(or to make one, starting with FROM <the image used by your container>) with:

RUN apt-get update && apt-get install gnupg

(as in this docker-vault-init Dockerfile)

Then check out "Adding GPG key inside docker container causes “no valid OpenPGP data found”".
This could be needed:

RUN apt-get install -y ca-certificates wget
