Hello, I have an instance of docker (the supported image). When I try to docker attach it just shows the cursor blinking on an empty line, there is no response to commands like ls.

Great! Please mark as solved so the topic gets closed. Glad that worked!

Done! But I’d still like to know what the problem was and How can I functionally attach?

Is it something like ./launcher enter app that you’re looking for? That’ll give you a shell prompt inside the container. I don’t know how to do it with docker directly, but maybe docker exec -it app bash

[image] Ed S: That’ll give you a shell prompt inside the container Indeed that is my objective, I want to sniff around the database tables. I will try docker exec -it app bash I thought that this was what docker attach was for, but I’m not an expert.

Looking further based on the hints fomr @pfaffman and @Ed_S, this answer from SO explained it well (accepted answer) [Andrew] How do I get a console-like connection into a Docker container's shell? docker, docker-container asked by Andrew on 04:12PM - 11 May 15 UTC EDIT: the point is that a web server is running on the image, so docker attach doesn’t work, but the exec command does

[image] Bastiaan Quast: Indeed that is my objective, I want to sniff around the database tables. Then maybe use the data explorer plugin. That’s a much better way to explore the database. But maybe you’d be interested in Administrative Bulk Operations
