ssh-keygen not present on container

[pdelaby]

Overview of the issue

To use the registry with a git repository, ssh and docker, the "ssh" page ( http://myurl:8761/#/ssh) explain how to generate a key pair with "ssh-keygen" :

Log in inside the container: docker exec -it <containerIdOrName> sh Generate an SSH key: ssh-keygen

However, this command doesn't exist on the container. In addition, the 'test' step to accept the rsa is mandatory.

Motivation for or Use Case

The documentation is detailed, so it shoud detail the steps to generate a keypair.

Reproduce the error

• Start and enter a registry container docker run --rm -i -t jhipster/jhipster-registry:v4.1.1 sh
• Try the given command : ssh-keygen
• Reponse : sh: ssh-keygen: not found

Suggest a Fix

I suggest updating the documentation.

Thoses are the steps I followed - I intend to use a volume to store the keys.

1. create a Dockerfile : ubuntu with openssh installed

FROM ubuntu:latest
RUN apt-get update
RUN apt-get -y install openssh-client 
RUN mkdir /root/.ssh

2. build the image docker build -t keygen-generator .

3. Start a container based on this image, and use the volume docker run --rm -i -t -v jhipster-registry-data:/root/.ssh keygen-generator bash

4. Generate the keys ssh-keygen -q -t rsa -N '' -f /root/.ssh/id_rsa

5. Accept the key for the host of you git repo (here, github) ssh -T [email protected] then type "yes"

6. The volume jhipster-registry-data now contains my keys, the know_host, and can be used with my jhispter-registry container.

JHipster Registry Version(s)

I'm using the image jhipster-registry:v4.1.1
