Description

SSHD server inside Gitea container does not allow more concurrent access. Our CD/CD infrastructure is based on SSH. So I had to put sshd_config template file on an external volume and customize it with:

MaxStartups ${SSHD_MAX_STARTUPS}
MaxSessions ${SSHD_MAX_SESSIONS}

The variables are environment variables passed by docker-compose environment.
After increasing the values, my environment became stable again.
