I developed a tool to execute BASH scripts on a server in a WebUI. This is what the tool looks like:

BashPanel uses SSH to execute commands on your docker host. You can deploy scripts and execute them directly from the WebUI. The SSH keys are mounted read-only.

Installation:

Setup SSH keys for the server:

# ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519_bashpanel -N ""
# cat ~/.ssh/id_ed25519_bashpanel.pub >> ~/.ssh/authorized_keys
# eval "$(ssh-agent -s)"
# ssh-add ~/.ssh/id_ed25519_bashpanel

The container must be permitted to read the keys. This usually works with these commands: You need to replace "USER" with your username. 

$ chmod 700 /home/USER/.ssh
$ chmod 600 /home/USER/.ssh/id_ed25519_bashpanel
$ chmod 644 /home/USER/.ssh/id_ed25519_bashpanel.pub

docker-compose.yml

services:
  bashpanel:
    image: byte21516/bashpanel:latest
    container_name: bashpanel
    restart: unless-stopped
    network_mode: host
    volumes:
      - ./bashpanel-scripts:/app/scripts                 # WebUI Upload/Download
      - /home/USER/.ssh/id_ed25519_bashpanel:/root/.ssh/id_ed25519:ro      # SSH key (private)
      - /home/USER/.ssh/id_ed25519_bashpanel.pub:/root/.ssh/id_ed25519.pub:ro  # SSH public key
    environment:
      - PORT=3001
      - HOST_USER=USER
      - SSH_KEY_PATH=/root/.ssh/id_ed25519

You can find the image on DockerHub.

You can find a mirror of the source code on GitHub.
