Add deploy keys to multiple projects

If you want to add the same deploy key to multiple projects in the same group, this can be achieved with the API.

First, find the ID of the projects you’re interested in, by either listing all projects: 

curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects"

Or finding the ID of a group: 

curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/groups"

Then listing all projects in that group (for example, group 1234): 

curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/groups/1234"

With those IDs, add the same deploy key to all: 

for project_id in 321 456 987; do
    curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
         --header "Content-Type: application/json" \
         --data '{"title": "my key", "key": "ssh-rsa AAAA..."}' \
         "https://gitlab.example.com/api/v4/projects/${project_id}/deploy_keys"
done
