Docker – Is it possible to start a shell session in a running container (without ssh)

docker

I was naively expecting this command to run a bash shell in a running container :

docker run "id of running container" /bin/bash

it looks like it's not possible, I get the error :

2013/07/27 20:00:24 Internal server error: 404 trying to fetch remote history for 27d757283842

So, if I want to run bash shell in a running container (ex. for diagnosis purposes)

do I have to run an SSH server in it and loggin via ssh ?

With docker 1.3, there is a new command docker exec. This allows you to enter a running docker:

docker exec -it "id of running container" bash

Edit: My answer is stale. I think that another answers is better.

~~RUN /bin/bash -c "source /usr/local/bin/virtualenvwrapper.sh"~~

Perhaps the StudentStatus field in your recordset is lowercase? Wrap it in a UCase()?

Also, you can really simplify that code for readability...

<%
Dim RspMsg, RspColor
If (UCase(rs_view("StudentStatus"))="OK") Then 
    RspMsg = "You are QUALIFIED to go for competition"
    RspColor = "#3300FF"
Else
    RspMsg = "You are NOT QUALIFIED to go for competition"
    RspColor = "#FF0000"
End If
