The next command **docker stop petclinic-client** in Lab 1.2 ( #20) (Elastic Observability Engineer) doesn’t work with error **“-bash: docker: command not found”**. None of docker commands work. Docker is either not installed or not visible to current user ![image001](https://us1.discourse-cdn.com/elastic/original/3X/5/3/530a5197e47e516163092d650762dcd8c0ac6599.png) ---

Can you let me know what the command prompt looks like for the terminal window you're attempting this command in? ---

here it is. So we SSH into `elasticsearch` as per instructions, so docker should be installed there. I think, this instruction misses to `exit` SSH, cause if we do so, it will return us to host , where docker is installed, and command is able to stop `petclinic-client` container ![elastic](https://us1.discourse-cdn.com/elastic/original/3X/a/f/af09b8bbafa17668eca4a6b39714577b7878e642.png) ---

Try opening a new terminal window, don't ssh anywhere, and run the docker command from the prompt reading "elastic@ip-172-31-33-148". ---

yes, it works. I found it was mentioned in desc above #20, but since it's important part to make it work and we rarely open new tabs, I suggest to make it bold somehow, so we may not miss it later ---

I'll open a ticket to fix this. ---

thank you. I understand it was primary my fault not carefully reading. I usually skim through text, especially comments, may be others do the same ---
