Decrypt with gpg from inside a docker container

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.

  • One Solution collect form web for “Decrypt with gpg from inside a docker container”

    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
    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
