Hi.
I am unable to connect to Azure Linux VM after installing Docker.
Port 22 for SSH is allowed in NSG.
I have to restore the VM to be able to connect.
Note: VM is behind Firewall
What do you mean not connecting? Can you give more details please?
I am unable to connect to VM via SSH after installing Docker.
In fact the VM stops responding midway through Docker installation.
After I restore the VM to a point before Docker was installed, the VM starts accepting connections through SSH.
I came to know that it has something to do with iptables.
Note : VM is behind firewall.
Do you have an understanding of the root cause of the issue? If you do, that's reassuring to hear.
I just know that Docker modifies iptables and this does not allow us to connect to VM via SSH.
how do I resolve this?
Could you kindly confirm the operating system you are currently running?
Please attempt this solution and inform me of your results.
Before installing a new Docker installation, please remove any older installations. Removing previous Docker versions will not lose the images, containers, volumes, and networks you have created.
sudo apt-get remove docker docker-engine docker.io containerd runcsudo apt update -ysudo apt install docker.io -ysudo snap install dockersudo systemctl status docker
I cannot remove docker as the VM disconnects while docker installation is in progress. It becomes unresponsive at around 80%, after which no matter what I do, VM doesn't connect.
I then have to restore the VM to a previous date and it starts working fine.
Could you try repeating the process once more? If it becomes unresponsive, please open a new terminal and use SSH to access it while leaving the previous method to continue.
Additionally, you have the option of creating a new temporary virtual machine and installing Docker using the instructions provided above. This will help you determine if you encounter the same issue. If not, you can then proceed with a storage swap.

i did
az vm run-command invoke --resource-group <RESOURCE_GROUP> --name <VM_NAME> --command-id RunShellScript --scripts "sudo apt-get remove --purge -y docker.io docker-ce docker-ce-cli containerd runc && sudo systemctl restart ssh"
