Trying to attach to docker images I pulled in from docker hub to figure out what the issues are...

I am new to docker however i cant figure out how to attach to the docker container to interface with the container.

Docker Newb Here

 

I usually run multiple vm's with with the apps installed native in the os and mod them to work for my app,

 

from what i have read i used docker attach [my container]

 

I get nothing from this command....

If I spell the container wrong I get told...

 

root@UNRAID:/run/lock# docker attach websync

Error: No such container: websync

root@UNRAID:/run/lock# docker attach WebSync

 

 

 

.... no response....

 

 

Thanks

I am still learning this, but try "docker ps" which will list all containers.  The id of the container appears to be different than the image name.

 

When you attach to the docker you may just attach to a running process and not actually have shell access.  I assume what you really want to do is get shell access to the docker ....

 

docker exec -it DOCKERID bash

Docker exec works with the image name, no need for ids.

I just do a :

 

docker ps

 

cut-n-paste the id into

 

docker exec -it <paste> bash

 

then if I want to run top

 

export TERM=xterm

 

I find it faster to cut-n-paste the ID than trying to remember/figure out the names

The names should exactly match the application name you provided in the UI so its very easy to remember values like "NZBGets" or "Transmission" or "EggDrop" or "PyTivo".

 

Its by far easier than anything else.

I wrote a little script to help me with that. You are welcome to use it.

 

I haven't used it recently, let me know if there is a problem.

Good to know.  I think was trying template name instead of the actual docker name.

That looks handy, I may borrow that
