At present, gitlab officially does not release the arm64 version of gitlab-runner, so it can only compile itself.
However, I have compiled the arm64 version and wrote a one-click installation script, the usage is as follows
If you are the root user
Bash <(curl -s -L https://git.io/fjJEO)
Sudo -E curl -s -L https://git.io/fjJEO | sudo -E bash -
Wait a moment after execution
