Basic ssh server with docker/podman

Hi this is my setup for sshing container.

Why?

Purpose of this is using with ssh and sshfs and gaining vscode/dev-containers functionality with any ide you desire.

Warning

Keep in mind that this docker file built with no security with mind. Its assumed that your computer's or your modem's firewall already blocking this ports to the outside. If you want to use it in internal networks, please harden it.

How to use it.

First, keep in mind that every time you started a new container, sshd key will change and ssh will warn you about it. You should remove ~/.ssh everytime for a new container.

you build it Dockerfile with:

docker build -t alpine-ssh .

then run it with:

docker run -p 2222:22 -it alpine-ssh

then connect to ssh with your terminal(default password is password):

ssh -p 2222 ed@yourlocalipaddress

then mount user ed's home folder with(default password is password):

sshfs -oport=2222 ed@yourlocalipaddress:/home/ed /your/desired/mount/point

change your local ip address with inet section of your network interface when running ip addr for example if it shows:

inet 192.168.1.122/44 brd 192.168.1.255 scope global dynamic noprefixroute wlan0

yourlocalipaddress should be 192.168.1.122.

After finished unmount with:

fusermount -u /your/desired/mount/point

I want to change default user

Sure default user's username defined in "USERNAME" variable and default password is in "PASSWORD", you can either change it in Dockerfile or define as variable when building container.
