Docker-node: gpg: not found

[anacir182]

Hi, I'm working on my docker setup and started to get this error every time I try to install node.
Can anyone please help?

Error is : + gpg --keyserver ha.pool.sks-keyservers.net --recv-keys 9554F04D7259F04124DE6B476D5A82AC7E37093B
/bin/sh: 1: gpg: not found

Below is my build:

Install gpg and dirmngr

apt-get install -y  gnupg dirmngr

Also, we're happy to help, but issues here should be focused on the docker node image, not general docker questions.
