Cannot get TeamCity to authenticate to GitHub with Default Private Key

I'm trying to get TeamCity to build my private GitHub repository. I'm able to successfully get my VCS root to pass the connection test when I explicitly set the path to the key file; however, despite lots of Googling, I can't get it to work when I use the 'Default Private Key' option. I get com.jcraft.jsch.JSchException: Auth fail.

Both my TeamCity server and build agent are running as a user called (gasp) teamcity, and the contents of C:\users\teamcity\.ssh\ include both a config and a key file, where the config is pointing to the key file. My config contains:

Host *
    IdentityFile ~/.ssh/github.key

I've tried a variety of different path styles, both Windows and Unix style, but none seem to work.

Again, it works fine if I use the private key setting and explicitly set the path to the key file, but not when I use the default private key, which I apparently need for my build agent to work.

Easiest solution for me was this:

  1. Upload your (OpenSSH) key under your Pipeline's project settings "SSH Keys" (as seen below):

    Pipeline - Project settings (ssh)

    Look at resource links for OpenSSH info (why/how)

  2. And then in VCS root settings, Update "Authentication Settings" as seen below:

    enter image description here

    • note: the username is; "git" (see 3rd resource)

  3. Make sure your "Fetch URL" look something like "[email protected]:ProjectName/RepositoryName.git" - (Note: Github equivalent is required here)

  4. Add your new key (see 1st resource)

Git looks for the .ssh folder by forming a path with %HOMEDRIVE%/%HOMEPATH%. I've found that even though the %USERPROFILE% environment variable is set correctly these are not set. If %HOMEDRIVE% is empty %SYSTEMDRIVE% will be used instead so by default it will look for .ssh folder in c:\ (or whatever your system drive is).

You can check the environment variables an agent has via the agent parameters tab when selecting an agent and what a build is using via the parameters tab of the build.

Solution 1

create .ssh folder in c:

Solution 2

Set environment variables for %HOMEDRIVE% & %HOMEPATH% to match where your userprofile is

Solution 3

git also can use %HOME% environment variable this is the full path i.e. equal %USERPROFILE%
