Operate on gitlab:
Put the public key on gitlab
Click the projects---your projects---project1--- gear icon settings
-repository---Deploy Keys--- enter key value-click Write access allowed
Other projects also use the same key, but enable it manually in the Deploy Keys interface
Test on jenkins-slave
Git clone git@192.168.1.14:group1/project1.git
Configure the slave node on master
System management-node management-create a new node-name jenkins-slave1, fixed node-label and name are the same-remote working directory: / data/jenkins on slave
-usage: use this node whenever possible (both free style and pipeline projects give priority to automatic use of this node)
-Startup method: ip--- credential of launch agent agents via SSH---host:slave-add
-root (password) of kind:username with password---username:salve
-ip---Host Key Verification Strategy:non verifying verification strategy of descriptin:slave
Specify that the pipeline task is built using slave
