add SSH KEY option 2 not working

[Phillip85]

Hi,

I am trying to use the "thecodingmachine/php:8.0-v4-apache-node14" image.
When I add an SSH-KEY like written in the docs (option 2) I get the following error:

Step 6/12 : FROM thecodingmachine/php:8.0-v4-apache-node14
 ---> 641d946688e4
Step 7/12 : RUN echo "$SSH_KNOWN_HOSTS" >> ~/.ssh/known_hosts
 ---> Running in 8a2f06c11e5a
Removing intermediate container 8a2f06c11e5a
 ---> d52a82980f21
Step 8/12 : RUN ssh-add <(echo "$SSH_PRIVATE_KEY")
 ---> Running in d656770df795
/bin/sh: 1: Syntax error: "(" unexpected

maybe a solution would be:

RUN echo "$SSH_KNOWN_HOSTS" >> ~/.ssh/known_hosts
RUN echo "$SSH_PRIVATE_KEY" >> ~/.ssh/id_rsa

@Phillip85 Can you try https://stackoverflow.com/a/46253163/6812729 ?

ssh-add - <<< "${SSH_PRIVATE_KEY}"

The following works for me:

RUN eval "$(ssh-agent -s)" && \
    echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add - > /dev/null
