I am attempting to pull from a private Gitlab repository within a gitlab-ci.yml script. I followed the instructions located here: https://docs.gitlab.com/ee/ci/ssh_keys and in addition, the conversation on this thread: https://gist.github.com/yannhowe/5ab1501156bd84c8ac261e2c17b8e3e0
The relevant chunk of the gitlab-ci.yml is:
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
- eval $(ssh-agent -s)
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- echo "$SSH_PRIVATE_KEY" | tr -d '\r' > ~/.ssh/id_rsa
- chmod 700 ~/.ssh/id_rsa
- ssh-add ~/.ssh/id_rsa
I added the private key into the CICD Variable section (and tried adding a line break at the end per one of the recommendations: https://gist.github.com/yannhowe/5ab1501156bd84c8ac261e2c17b8e3e0) but to no avail. I am constantly seeing the following with the Gitlab job output:
Error loading key "/root/.ssh/id_rsa": invalid format
Thoughts on what I am doing wrong?
BTW: I added the same id_rsa to my ssh agent through the command: ssh-add ~/.ssh/id_rsa on my Macbook and it executed fine so I am stumped on what Docker thinks is wrong.
Unfortunately, I was not copying:
-----BEGIN RSA PRIVATE KEY-----
......
-----END RSA PRIVATE 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."
I've a problem with my GitLab CI / CD pipeline: It's not connecting to my server during the deployment.
I've followed the instructions on the GitLab page and created a key pair for my server locally and tried it out - works perfectly.
Now I've switched to GitLab and created a file variable with the content of my private key file:
After that I've added a deployment section to my .gitlab-ci.yml file:
stages:
- deploy
deploy:
stage: deploy
before_script:
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- touch ~/.ssh/known_hosts
- ssh-keyscan 136.xxx.xxx.xx >> ~/.ssh/known_hosts
- chmod 644 ~/.ssh/known_hosts
script:
- echo "Deploying to server..."
- ssh -i $IDENTITY ftp#136.xxx.xxx.xx "echo Hallo"
only:
- master
But when I execute the script, I'm getting this error:
$ ssh -i $IDENTITY ftp#136.xxx.xxx.xx "echo Hallo"
###########################################################
# WARNING: UNPROTECTED PRIVATE KEY FILE! #

What I'm doing wrong here? I don't get it.
Thanks to VonC. This is how I solved the problem with his help:
First I've changed the variable from file to variable. After that I've modified my deploy script:
deploy:
stage: deploy
before_script:
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
- eval $(ssh-agent -s)
- echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add - > /dev/null
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- touch ~/.ssh/known_hosts
- ssh-keyscan 136.xxx.xxx.xx >> ~/.ssh/known_hosts
- chmod 644 ~/.ssh/known_hosts
script:
- echo "Deploying to server..."
- cd /builds/john/test-website/frontend/
- ls
- ssh ftp#136.xxx.xxx.xx "ls"
only:
- master
You might want to consider a custom variable of type Variable instead of type file.
That way, GitLab won't create a temporary file with the wrong permission.
But your pipeline can:
create the relevant file (with the right permission 600),
use it in ssh -i, and
delete it immediately.
Hello everyone i need your help plz, i'm using gitlab ci/cd and trying to deploy my .jar application to an ubuntu server, i configured my gitlab project with a windows runner with shell executor. i configured a key based access on the runner to avoid being prompt for a password;
the following command runs successfully when i login to the runner machine and use it's powershell :
scp -i C:\Users\Administrators\ssh\id_rsa myapp-0.0.1-SNAPSHOT.jar username#myubuntuserver:/
but when i'm using the above commande in my .yml file to copy the .jar on the server, it doesn't give any response until the job fail due to timeout
i tried also the solution proposed here https://docs.gitlab.com/ee/ci/ssh_keys/ by setting an SSH_PRIVATE_KEY variable on my project but i'm unable to adapt the given 'before_script' to my windows runner.
this is the before_script proposed in the documentation (above link):
before_script:
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
- eval $(ssh-agent -s)
- echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
when the previous scp command is replaced by this:
ssh -iv C:\Users\Administrators\ssh\id_rsa username#myubuntuserver
i get the following output:
the image
Thanks in advance
It works after doing the following steps:
1) configuring the runner (shell executor) on ubuntu 18.04
2) Then from the terminal login as the gitlab-runner user: sudo su - gitlab-runner
3) run ssh-keygen -t rsa
4) run ssh -i ~/.ssh/id_rsa username#myubuntuserver:
5) run cat ~/.ssh/id_rsa.pub | ssh username#myubuntuserver "mkdir -p ~/.ssh && touch ~/.ssh/authorized_keys && chmod -R go= ~/.ssh && cat >> ~/.ssh/authorized_keys"
5) now you can add the following to your job script (yml file) and it should work:
- scp -i ~/.ssh/id_rsa fileToCopy username#myubuntuserver:/mydirectory
#you can execute multiple commands at a time, for ex:
- ssh username#myubuntuserver " mv /mydirectory/myapp-0.0.1-SNAPSHOT.jar /mydirectory/myapp.jar "
Hope it will help
If ssh -iv C:\Users\Administrators\ssh\id_rsa username#myubuntuserver does not work, that may be because of the C: part, which confuses ssh into thinkig C is the name of the server!
A Unix-like path would work:
ssh -iv /C/Users/Administrators/ssh/id_rsa username#myubuntuserver
But, as the OP Medmahmoud comments, this supposes the public key has been published on the server:
Configure the runner on ubuntu18.04.
Then from the terminal login as the gitlab-runner user:
sudo su - gitlab-runner - run ssh-keygen -t rsa
ssh -i ~/.ssh/id_rsa username#myubuntuserver
cat ~/.ssh/id_rsa.pub | ssh username#myubuntuserver \
"mkdir -p ~/.ssh && touch ~/.ssh/authorized_keys && chmod -R go= ~/.ssh && cat >> ~/.ssh/authorized_keys"
Now from your yml file the following should work:
- scp -i ~/.ssh/id_rsa pom.xml username#myubuntuserver:/mydirectory
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>

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;"
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
