sudo -u git ssh-keygen -t rsa -b 4096 -C "Gitea Host Key"
```
Still on the host, symlink the container `.ssh/authorized_keys` file to your git user `.ssh/authorized_keys`.
Now, proceed with one of the points given below:
- symlink the container `.ssh/authorized_keys` file to your git user `.ssh/authorized_keys`.
This can be done on the host as the `/var/lib/gitea` directory is mounted inside the container under `/data`:

```
Lastly, Gitea makes `authorized_keys` backups by default. This could be a problem
as the symbolic link made to `authorized_keys` previously could end up pointing
to an old backup. To resolve this, please put the following into your Gitea
config:
```
[ssh]
SSH_BACKUP_AUTHORIZED_KEYS=false
```
- mount your `.ssh` directory directly into the container i.e. add the
following to the `volumes` section of your Docker container config:
```
- /home/git/.ssh/:/data/git/.ssh/
```
Now you should be able to use Git over SSH to your container without disrupting SSH access to the host.
Please note: SSH container passthrough will work only if using opensshd in container, and will not work if
