jenkins/hudson can't connect to github repo

Question

I am on Ec2 with the base amazon ami linux- I have installed jenkins but when I go to pull the repo from github I am given the following error:

Building in w         


        

Answer 1

He following helped me:

Login under Jenkins

sudo su jenkins

Copy your github key to Jenkins .ssh folder

cp ~/.ssh/id_rsa_github* /var/lib/jenkins/.ssh/

Raname the keys

mv id_rsa_github id_rsa
mv id_rsa_github.pub id_rsa.pub

Answer 2

If you log in as jenkins you can do

ssh -i ~/.ssh/id_rsa git@github.com

where ~/.ssh/id_rsa is the path/to/your/ssh/key and it will prompt for the password and add to the known_hosts file

Answer 3

The error seems to be: host key verification failed.

You should log into your Jenkins host as the Jenkins user and run:

ssh git@github.com

Then answer yes to the prompt about the host key. This only needs to be done once.

Alternatively you could add "StrictHostKeyChecking no" to ~jenkins/.ssh/config.

Answer 4

You need to add the ssh key of jenkins to you github user.

Generate ssh key

Go to:

Github->Settings(Top right)->SSH Keys(Left Pane)->Add SSH Key

Answer 5

1) Switch User into your jenkins account

su jenkins

2) Create the key without a passphrase

3) ssh git@github.com

That worked perfectly for me.

You may need to create a password for the jenkins account, if so use sudo passwd jenkins

Answer 6

I'm using a single jenkins machine to check out multiple github repositories and had similar problems when setting it up. What I ended up doing was configuring an SSH config file for jenkins so that SSH would automatically know which id file to associate with each repository.

/var/lib/jenkins/.ssh/config:

Host github-ABC
  HostName github.com
  User git
  IdentityFile /var/lib/jenkins/.ssh/id_rsa_ABC

In the Jenkins project config under source code management, I used this as the repository name:

git@github-ABC:user/repo.git

Finally, I use the SSH public key as a deploy key in the github repository.
