I just installed gitea using docker on Linux mint 19, I used /data with old gitea instalation so I have a populate db and repositories. It seems work correctly when I access to the web.
The problem is using SSH:
➜ /tmp sudo git clone git@gitealocal:felipe/test.git
Cloning into 'test'...
ssh: connect to host gitealocal port 22: Connection refused
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
➜ /tmp ssh -vT gitealocal

I check permissions on directory and files /var/lib/gitea/ssh
but it seems right. drwx------
