Gitea log:

gitea | Accepted publickey for git from 172.16.0.29 port 18156 ssh2: ED25519 SHA256:JWL4pxjv2NJ6DgI3LZz2AzVu+TvbK7b9vF8OcfCvZtE
gitea | Received disconnect from 172.16.0.29 port 18156:11: disconnected by user
gitea | Disconnected from user git 172.16.0.29 port 18156

I tried to use RSA and ed25519. I tried:

  • Update the '.ssh/authorized_keys' file with Gitea SSH keys.
  • Update the '.ssh/authorized_principals' file with Gitea SSH principals.

I also tried to make same actions on https://try.gitea.io/. I've created a new account and added ssh key in user settings. Cloning was successful.

I've seen some similar issues since 2017 but I didn't saw any solution.

Ssh works fine with other resources (GitLab, Linux server, etc)

About permissions. I set git as a user and chmod 777 to ssh folder but when I restart docker-compose ssh get next permissions:

root@homesrv1:~/gitea/data/ssh# ls -l
итого 32
-rw------- 1 root root 1381 сен 21 20:01 ssh_host_dsa_key
-rw------- 1 root root  607 сен 21 20:01 ssh_host_dsa_key.pub
-rw------- 1 root root  513 сен 21 20:01 ssh_host_ecdsa_key

-rw------- 1 root root 1823 сен 21 20:01 ssh_host_rsa_key
-rw------- 1 root root  399 сен 21 20:01 ssh_host_rsa_key.pub

I've changed permissions by docker exec but it didn't help

I've read the docker manual again. Wrong line in config:
