odd behavior exposing ssh login port?

[jeffsauer]

using the buster lite image, I configured the ssh service to auto start with systemctl enable ssh.service

However, when trying to connect from a ssh client, I kept getting:

ssh -p 5022 [email protected]
kex_exchange_identification: read: Connection reset by peer
Connection reset by 127.0.0.1 port 5022

The only way i could connect was by adding network_mode: host to my docker compose file, even though docker says published ports are ignored in host mode.

Here is my docker compose file:

dockerpi:
image: lukechilds/dockerpi:vm
container_name: dockerpi
command: pi3
environment:
- PUID=1000
- PGID=1000
- TZ=America/Phoenix
volumes:
- /home/jsauer/docker/appdata/dockerpi/buster_filesystem.img:/sdcard/filesystem.img
network_mode: host
ports:
- 5022:22/tcp
restart: unless-stopped

Got same problem even with newtork_mode it doesn't works

Seems the reason is ssh is not enabled by default, need to enable the service using sudo systemctl enable ssh once logged in. I think another way coud be edit the base image and add a .ssh file inside /boot partition.

No clue if there is an easier way to auto enable ssh on boot, no easy way to send commands to the vm from outside docker
