Alpine SSHD (Dropbear)

This is a small Alpine-based container using openssh-sftp-server and Dropbear SSH.

The intended usage is to (temporary) access/modify shared volumes by SSH/SFTP.

This is standalone fork, of now abandoned project sjourdan/alpine-sshd.

Usage

It takes 2 variables: USER and PASSWORD, both in cleartext. Redirect the TCP/22 port to whatever port you want.

docker run -d \
-p 2222:22 \
-e USER=myusername \
-e PASSWORD=mypassword \
nlss/sshd

Then you can use this container to SFTP and/or SSH:

sftp -P2222 user1@192.168.99.100
user1@192.168.99.100's password:
Connected to 192.168.99.100.
sftp> pwd
Remote working directory: /home/user1
sftp>

Dropbear Notes

Options used in this container:

-R              Create hostkeys as required
-F              Don't fork into background
-E              Log to stderr rather than syslog
-m              Don't display the motd on login
-w              Disallow root logins
-g              Disable password logins for root
