Azure Webapp: 'docker: command not found' after I installed docker

I'm running an App Service on Azure. I can SSH into the Linux terminal.

Linux version: Debian 9.13 (Debian GNU/Linux 9.13 (stretch))

I'm getting the message 'docker: command not found' even though I just installed Docker.

I installed docker in this way:

root@682bfc3257d2:/home# apt-get install docker Reading package lists... Done Building dependency tree Reading state information... Done docker is already the newest version (1.5-1+b1). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Solution

  • Initially, I was getting the same error even after running apt-get install docker.

    Later, I followed this document and could install Docker in Azure App Service->SSH.
