如何设置多个Github部署密钥（npm，yarn）？

Question

I have an npm project that depends on several private Github repositories. I am deploying the project on staging server, and I have set up separate deploy keys for each private repository, as Github does not allow to use the same key for each. I have set up ~/.ssh/config like this:

Host 1.github.com
        HostName github.com
        User git
        PreferredAuthentications publickey
        IdentityFile ~/.ssh/key-1
        StrictHostKeyChecking no

Host 2.github.com
        HostName github.com
        User git
        PreferredAuthentications publickey
        IdentityFile ~/.ssh/key-2
        StrictHostKeyChecking no

Host 3.github.com
        HostName github.com
        User git
        PreferredAuthentications publickey
        IdentityFile ~/.ssh/key-3
        StrictHostKeyChecking no

In package.json, I have the following private Github repository dependencies:

"project1": "git+ssh://git@github.com/myorg/project1.git",
"project2": "git+ssh://git@github.com/myorg/project2.git",
"project3": "git+ssh://git@github.com/myorg/project3.git"

However, this does not work and I'm getting Permission denied (publickey) error. The projects are also being used by users who access the repositories with their Github accounts.

How do I get the keys working?

If you want to use different keys for different github accounts, you need to modify the git urls by using the alias defined in the configuration files, such as:

"project1": "git+ssh://git@1.github.com/myorg/project1.git",
"project2": "git+ssh://git@2.github.com/myorg/project2.git",
"project3": "git+ssh://git@3.github.com/myorg/project3.git"
