Using Multiple Deploy Keys

One way to pull code from Git to a server is to add a public SSH key as a Deploy Key in the Repo Settings. There is a problem though that each Deploy Key can only be used on one GitHub repo which requires multiple Keys. You then have the problem of telling Git which key to use with which repo.

1. Generate an SSH keypair per repo as usual (albeit with a unique filename) and add it to the repo as a Deploy Key.

2. Create a .ssh/config file which looks similar to the following -

Host github.com-data_extract
        Hostname github.com
        IdentityFile=/home/ukrdc/.ssh/data_extract_key

Host github.com-ukrdc_database
        Hostname github.com
        IdentityFile=/home/ukrdc/.ssh/ukrdc_database_key

Host github.com-ukrr_quarterly_extract
        Hostname github.com
        IdentityFile=/home/ukrdc/.ssh/ukrr_quarterly_extract_key

Host github.com-data_extract

This is the important part which we’ll be using in the git clone command. I have used the same value as the repo name (as with the key filenames) but I believe it just needs to be a unique value.

3. Clone using a command similar to -

git clone git@github.com-data_extract:renalreg/data_extract.git

Note the modified hostname to match the reference in the config file.
