Why SSH ?
If you do not have direct access to the server that runs your IRIS Docker container
you still may require access to the container outside "iris session" or "WebTerminal".
With an SSH terminal (PuTTY, KiTTY,.. ) you get access inside Docker, and then, depending
on your needs you run "iris session iris" or display/manipulate files directly.
Note:
This is not meant to be the default access for the average application user
but the emergency backdoor for System Management, Support, and Development.
This project is based on templates for InterSystems ObjectScript Github repository.
There a few significant extensions:
- docker-compose.yaml exposes port 22 for SSH
- Dockerfile installs SSH server and prepares Server start. You may observe a significant bunch of updates as the underlying Ubuntu is not very fresh
The rest is pretty default for InterSystems IRIS Community Edition in a docker container.
Prerequisites
Make sure you have git and Docker desktop installed.
Installation
Clone/git pull the repo into any local directory
$ git clone https://github.com/rcemper/SSH-for-IRIS-container.git
Open the terminal in this directory and run:
$ docker-compose build
Run the IRIS container with
$ docker-compose up -d
How to Test it:
If you didn't assign a fixed port to projected container port 22 you may run
$ docker ps
e37392a1c7c3 ssh-for-iris-container "/bin/sh -c '/iris-m…" 2 hours ago Up 2 hours (unhealthy)
2188/tcp, 54773/tcp,
0.0.0.0:41022->22/tcp, 0.0.0.0:41773->1972/tcp, 0.0.0.0:42773->52773/tcp, 0.0.0.0:49716->53773/tcp
and see the assigned_port for port 22 in the container 0.0.0.0:41022->22/tcp, (here it's 41022).
Next, you connect with PuTTY over SSH to server:assigned_port
Log in as irisowner + the PW of your choice and you are in your container.
This is similar as with docker-compose exec iris sh in a local docker instance.
Example:
login as: irisowner
irisowner@localhost's password:
