How to install SSH in app service container

Question

I need to login to a linux container hosted in an app service via SSH (the image doesn't have it installed) in order to copy some files. Is there a way to do this via the portal? I'd like to avoid extending the image if possible. I tried fiddling with the startup command available in the UI with no luck.

Thanks!

Why not give any response? Do you still want to solve the problem? Or you just ignore the help? — Charles Xu, May 21 '20 at 07:49

For the Web App, SSH is supported, but you need to configure the SSH yourself when you use the custom image. Only the built-in images which Azure Web App provided can use the SSH directly without configuring yourself. When you use the built-in image, you can go into the Kudu and the SSH is already configured there.

I am running my Docker Container in local machine, to Use SSH utility I have perform following steps

Step 1: Login to Docker Container using docker command

$ docker exec -it <container_id or container_name> /bin/bash

Step 2: Install SSH Server

$ apt-get update && apt-get install -y openssh-server

**Step 3 Create SSH-keypair in your local machine **

You can Skip this step if you have SSH-keypair in your ~/.ssh directory

$ ssh-keygen

Keep Default Path for storing Key Pair.
and for this Enter passphrase (empty for no passphrase): Just press Enter

Step 4: Copy the Content of Public key file to Docker ~/.ssh/authorized_keys file

From Local machine

$ cat ~/.ssh/id_rsa.pub

Now Copy that Public Key

Inside Docker container

$ mkdir -p ~/.ssh && chmod 700 ~/.ssh

$ echo "<Public-Key content>" > ~/.ssh/authorized_keys

$ chmod 600 ~/.ssh/authorized_keys

Step 5: Update SSH Configuration and restart SSH Service Inside Docker Container

Open file /etc/ssh/sshd_config and remove comment from following line

PubkeyAuthentication yes

This command is use to restart SSH Service to affect the changes.

$ service ssh restart

and Check the status of SSH Service to check it's running or not

$ service ssh status

Step 6: Get Docker Container I.P.

From Local machine run following Command

$ docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <container_name or container_id>

Step 7:Perform SSH

$ ssh root@<Container_IP>

You can also use SCP.

$ scp <file_name> root@<container_ip>:

"apt-get update && apt-get install -y openssh-server" gives "13: Permission denied" — Edgaras, Aug 09 '23 at 15:19
