Step 1: First of all, try to find your active container by running
# docker ps
or
# docker ps -a
Step 2: If the container is not running,
# docker start your_id
Step 3: If we use attach we can use only one instance of shell.
# sudo docker attach 665b4a1e17b6 #by ID Read complete tutorial click here

Thanks for this practical and straightforward explanation — gaining shell access to a running instance can be confusing the first few times, and your step-by-step walkthrough makes it feel much more approachable. I especially appreciated how you explained common configuration requirements and security considerations, because understanding why certain steps work (or don’t) is just as important as following them. The clarity in your examples helps bridge that gap between concept and execution, which is something many tutorials miss. If I could suggest one enhancement, it might be to include a quick troubleshooting section for errors people often run into — that would make it even more helpful for those moments when things don’t go as expected. Overall, this feels like a very useful resource for anyone learning how to interact with cloud instances via SSH or Bash — thanks again for sharing!
ReplyDeleteThanks for this practical guide! Accessing a running Docker container’s shell is a key debugging skill, and your step‑by‑step explanation makes it easy to follow. Using docker exec -it /bin/bash is the recommended way to get an interactive shell, while docker attach connects to the main process — both are useful in the right context. It’s also worth noting that running a full SSH server inside a container is generally not necessary and can introduce security and complexity issues; Docker’s built‑in commands give you the access you need without that overhead.
