Trouble with OpenVPN in Gitlab Pipeline - ssh

So I'm trying to connect to a VPN to my server in order to pull the project trough gitlab, this is my gitlab-ci.yml file:
image: cypress/base:10
stages:
- deployment
deploy:
stage: deployment
before_script:
## VPN
- which openvpn || (apt-get update -y -qq && apt-get install -y -qq openvpn) # Install openvpn if not available.
- cat <<< $CLIENT_OVPN > /etc/openvpn/client.conf # Move vpn config from gitlab variable to config file.
- cat <<< $VPN_U > /etc/openvpn/pass.txt # Move vpn user from gitlab variable to pass file.
- cat <<< $VPN_P >> /etc/openvpn/pass.txt # Move vpn password from gitlab variable to pass file.
- cat <<< "auth-user-pass /etc/openvpn/pass.txt" >> /etc/openvpn/client.conf # Tell vpn config to use password file.
- cat <<< "log /etc/openvpn/client.log" >> /etc/openvpn/client.conf # Tell vpn config to use log file.
- openvpn --config /etc/openvpn/client.conf --daemon # Start openvpn with config as a deamon.
- sleep 30s # Wait for some time so the vpn can connect before doing anything else.
- cat /etc/openvpn/client.log # Print the vpn log.
- ping -c "server IP" <IP> # Ping the server I want to deploy to. If not available this stops the deployment process.

## SSH
## Inspiration for gitlab from https://docs.gitlab.com/ee/ci/ssh_keys/
## Inpsiration for new key from https://www.thomas-krenn.com/de/wiki/OpenSSH_Public_Key_Authentifizierung_unter_Ubuntu
##
- which ssh-agent || (apt-get update -y -qq && apt-get install openssh-client -y -qq) # Install ssh-agent if not available.
- eval $(ssh-agent -s) # Run ssh-agent.
- mkdir -p ~/.ssh # Create ssh directory.
- cat <<< $SSH_PRIVATE_KEY > ~/.ssh/id_rsa # Move ssh key from gitlab variable to file.
- chmod 700 ~/.ssh/id_rsa # Set permissions so only I am allowed to access my ssh key.
- ssh-add # Add the key (no params -> default file name assumed).
- cat <<< $SSH_KNOWN_HOSTS_DMS > ~/.ssh/known_hosts # Add the servers SSH Key to known_hosts prevent man in the middle attack.
script:
- ssh root#"server IP" "cd ../var/www/html/"projetct-name" && git checkout master && git pull && exit"
only:
- main
I've been going around in circles for two days now, but right now I'm getting this feedback on the deploy job

How am I able to push to the Acquia repo but have a public key error when its time to ssh?
Not sure how to go about from here.
How can I ssh into the remote server and cd into the intended directories?

Gitlab CI/CD issue with SSH config file

I am trying to deploy my first project to my production server. Here is the script for the deployment stage:
deploy_production:
stage: deploy
script:
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
- eval $(ssh-agent -s)
- ssh-add <(echo "$SSH_PRIVATE_KEY")
- mkdir -p ~/.ssh
- '[[ -f /.dockerenv ]] && echo -e "ssh -p 69" "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'
- ./vendor/bin/envoy run deploy
environment:
name: production
when: manual
only:
- main
When I run the stage, I get this error :
[myServer#xxx.xxx.x.x]: /home/php/.ssh/config: line 1: Bad configuration option: ssh
[myServer#xxx.xxx.x.x]: /home/php/.ssh/config: terminating, 1 bad configuration options
[✗] This task did not complete successfully on one of your servers.
Why is it trying to access the SSH on this path :
/home/php/.ssh/config
Why is it trying to access the SSH on this path :
This should be related to the account used by gitlab-ci: it is supposed to look for SSH settings in $HOME/.ssh: display first what $HOME is.
If you look at the official documentation, you will see an SSH setup relies on proper rights associated to SSH folders/files:
efore_script:
##
## Install ssh-agent if not already installed, it is required by Docker.
## (change apt-get to yum if you use an RPM-based image)
##
- 'command -v ssh-agent >/dev/null || ( apt-get update -y && apt-get install openssh-client -y )'
##
## Run ssh-agent (inside the build environment)
##
- eval $(ssh-agent -s)
##
## Add the SSH key stored in SSH_PRIVATE_KEY variable to the agent store
## We're using tr to fix line endings which makes ed25519 keys work
## without extra base64 encoding.
## https://gitlab.com/gitlab-examples/ssh-private-key/issues/1#note_48526556
##
- echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -
##
## Create the SSH directory and give it the right permissions
##
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
I mention before a chmod 400 my_private_key if you store a key in ~/.ssh.
And to be safe, I would add a chmod 600 ~/.ssh/config.
The point is: if the rights are to opened, SSH will refuse to operate.

Gitlab CI cannot connect with SSH to remote server using SSH key

So, I want to deploy my Gitlab pipelines onto a server with SSH. This is my script .gitlab-ci :
test_job:
stage: test
variables:
GIT_STRATEGY: none # Disable Gitlab auto clone
before_script:
- 'command -v ssh-agent > /dev/null || ( apk add --update openssh )'
- eval $(ssh-agent -s)
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- echo "${SSH_PRIVATE_KEY}" | tr -d '\r' > ~/.ssh/id_rsa
- chmod 600 ~/.ssh/id_rsa
- ssh-add ~/.ssh/id_rsa
# Add server to known hosts
- ssh-keyscan ${VM_IPADDRESS} >> ~/.ssh/known_hosts
- chmod 644 ~/.ssh/known_hosts
# Verify that key has been registered
- ls ~/.ssh -al
# Verify server connection
- echo "Ping server"
- ping ${VM_IPADDRESS} -c 5
script:
# Pull Git project on remote server
- echo "Git clone from repository"
- ssh -o PreferredAuthentications=publickey ${SSH_USER}#${VM_IPADDRESS} "
rm -rf /tmp/src/${CI_PROJECT_NAME}/ &&
git clone https://gitlab-ci-token:${CI_BUILD_TOKEN}#gitlab.my-domain.fr/user/project.git /tmp/src/${CI_PROJECT_NAME}/
"
$SSH_PRIVATE_KEY contains my private SSH key I use daily to connect on that server. It works perfectly in normal time. ${SSH_USER} and ${VM_IPADDRESS} contain my username and the server address. I already checked that all the values in these parameters are correct on worker.
This is the message I have when trying this script :
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
I'm quite stuck with this actually :(. Any help :) ?
Adding my public key id_rsa.pub to ssh authorized_keys file in the server has solved the problem for me. And you need to make sure of adding your public key to your SSH keys in your Gitlab profile.
Also, it's good to note that:
"Add the public key to the services that you want to have an access to from within the build environment. If you are accessing a private GitLab repository you must add it as a deploy key."

how to execute commands via ssh shell runner from private gitlab to private server

Situation:
shell gitlab runner, certificate configured, ssh connected as follows:
ssh-keygen --> id_rsa & id_rsa.pub
ssh-copy-id <user>#<remotehost>
ssh <user>#<remotehost> works as designed
id_rsa -> gitlab cicd variable called 'SSH_PRIVATE_KEY'
gitlab-ci as follows:
before_script:
- echo "Before script section"
# Install ssh-agent if not already installed, it is required by Docker.
# (change apt-get to yum if you use a CentOS-based image)
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
# Run ssh-agent (inside the build environment)
- eval $(ssh-agent -s)
# Add the SSH key stored in SSH_PRIVATE_KEY variable to the agent store
- ssh-add < ~/.ssh/id_rsa
- ssh-add -l
build1:
stage: build
script:
- echo "Pulling on Dev\n"
- ssh -A <user>#<remotehost>
- hostname
- ssh-agent bash -c 'hostname'
- ssh-agent bash -c 'awk "NR==1{print;exit}" /etc/php7/php.ini'
Complication:
when executing commands via gitlab-ci after the ssh connection, it seems to be executed on the gitlab machine. (php is installed on the ssh'ed system, not on gitlab)
See gitlab job output below:
...
eval $(ssh-agent -s)
Agent pid 1234
$ ssh-add < ~/.ssh/id_rsa
Identity added: /home/gitlab-runner/.ssh/id_rsa (/home/gitlab-runner/.ssh/id_rsa)
$ ssh-add -l
4096 SHA256:<KEY> /home/gitlab-runner/.ssh/id_rsa (RSA)
# same behaviour with ssh -T <user>#<ipaddress> -p <portnumber>
$ ssh -A <user>#<ipaddress> -p <portnumber>

gitlab
$ ssh-agent bash -c 'awk "NR==1{print;exit}" /etc/php7/php.ini'
awk: cannot open /etc/php7/php.ini (No such file or directory)
In what way do I need to configure the system, so that the commands are actually run on the ssh'ed system?
I'm currently working with a solution which seems a bit too dirty for me.
In the gitlab-ci I'm pulling and running phpunit as follows
ssh -T <user>#<remotehost> "cd /var/www/projectfolder; git pull https://<gitlabUser>:$GITLAB_TOKEN#<privateGitlab>/<gitRepo>.git;"
ssh -T <user>#<remotehost> "cd /var/www/projectfolder/tests; phpunit;"
ie, I'm using a new ssh each time I'd like to run a command, which doesnt quite seem right to me. Any suggestions are welcome!
#til As per your suggestion request, single ssh command...
ssh -T <user>#<remotehost> "cd /var/www/projectfolder; git pull https://<gitlabUser>:$GITLAB_TOKEN#<privateGitlab>/<gitRepo>.git; cd /var/www/projectfolder/tests; phpunit;"

Gitlab CI - SSH Permission denied (publickey,password)

I've been trying to setup CD for my project. My Gitlab CI runner and my project will be on same server. I've followed https://docs.gitlab.com/ee/ci/examples/deployment/composer-npm-deploy.html but I keep getting SSH Permission denied (publickey,password). error. All my variables, private key and other variables set correctly in project settings.
I've created my ssh key with ssh-keygen -t rsa -C "my.email#example.com" -b 4096 command with no passphrase and set my PRODUCTION_PRIVATE_KEY variable with content of ~/.ssh/id_rsa file.
This is my gitlab-ci.yml:
stages:
- deploy
deploy_production:
stage: deploy
image: tetraweb/php
before_script:
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
- eval $(ssh-agent -s)
- ssh-add <(echo "$PRODUCTION_PRIVATE_KEY")
- mkdir -p ~/.ssh
- echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config
- apt-get install rsync
script:
- ssh $PRODUCTION_SERVER_USER#$PRODUCTION_SERVER
- hostname
only:
- master
And this is output from Gitlab CI runner:

Thanks in advance.
You need to add the public key to the server so it would be recognized as an authentication key. This is, paste the content of the public key corresponding to the private key you are using to the ~/.ssh/authorized_keys on the $PRODUCTION_SERVER.
This is the script that worked to me:
before_script:
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
- mkdir -p ~/.ssh
- echo "$SSH_PRIVATE_KEY" | tr -d '\r' > ~/.ssh/id_rsa
- chmod 700 ~/.ssh/id_rsa
- eval "$(ssh-agent -s)"
- ssh-add ~/.ssh/id_rsa
- ssh-keyscan -t rsa 64.227.1.160 > ~/.ssh/known_hosts
- echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config
- chmod 644 ~/.ssh/known_hosts
And I had to unprotect the variable as well.
The following can be used alternatively
some_stage:
- eval $(ssh-agent -s)
- cd ~
- touch id.rsa
- echo "$SSH_PRIVATE_KEY" > id.rsa
- chmod 700 id.rsa
- ssh -o StrictHostKeyChecking=no -i id.rsa $SSH_USER#$SERVER
Something important too...
The permissions of the ~/.ssh/authorized_keys file should be 600.
It can also be due to restrictions on users you can ssh into.
In my case, on the server, I got the following tail -f /var/log/auth.log:
..
Sep 6 19:25:59 server-name sshd[7943]: User johndoe from WW.XX.YY.ZZ not allowed because none of user's groups are listed in AllowGroups
..
The solution consists in updating the AllowGroups directive on the server's file /etc/ssh/sshd_config:
AllowGroups janesmith johndoe
In our case, we were clueless until we add the flag -v to the SSH command (we knew the public key setup was OK because we were able to connect to this instance from our laptop using the private key).
We saw this :
debug1: Offering public key: ... RSA SHA256:... agent
95debug1: send_pubkey_test: no mutual signature algorithm
And understood the situation thanks to the two links below : our key was generated with RSA format which is considered legacy on up-to-date openssh versions.
https://confluence.atlassian.com/bitbucketserverkb/ssh-rsa-key-rejected-with-message-no-mutual-signature-algorithm-1026057701.html
https://transang.me/ssh-handshake-is-rejected-with-no-mutual-signature-algorithm-error/
So you have two solutions :
generate a new key using ed25519 format and setup the public key on your instance
use this extra flag below in your ssh command
It should be a temporary workaround :
ssh -o PubkeyAcceptedKeyTypes=+ssh-rsa -o StrictHostKeyChecking=no your_user#your_instance_url "your command"
I hope it can help you if you are reading this.
Regards!
Add the public key (corresponding to the private key) to authorized keys.
Just a new line with you pub key:
cat /root/.ssh/id_rsa.pub.pub >> /root/.ssh/authorized_keys
And also add the pub key to gitlab ssh keys section Profile > Keys
