Docker. How to get bash\ssh inside running container (run -d)?


$ sudo docker attach 665b4a1e17b6 #by ID
$ sudo docker attach loving_heisenberg #by Name
$ root@665b4a1e17b6:/# 

UPDATE: (docker >= 1.3) Thanks to WiR3D user who suggested another way to get container’s shell. If we use attach we can use only one instance of shell. So if we want open new terminal with new instance of container’s shell, we just need run the following:

$ sudo docker exec -i -t 665b4a1e17b6 bash #by ID
$ sudo docker exec -i -t loving_heisenberg bash #by Name
$ root@665b4a1e17b6:/#

This is problably because the .dev and .local are now valid top level extensions.

i had to solve this, add “search home.local” to “/etc/resolv.conf”
(actually added this to “/etc/resolvconf/resolv.conf.d/head”)

etckeeper + git issue on trusty

latest Git version requires manually setting the, if the email cannot be auto-detected.

In combination with etckeeper configured with Git, this can give an error (example bellow).

To prevent this, make sure “/etc/hosts” contains a FQDN for the current hostname of your machine.

From man hostname:

The recommended method of setting the FQDN is to make the hostname be an alias for the fully qualified name using /etc/hosts, DNS, or NIS. For example, if the hostname was
“ursula”, one might have a line in /etc/hosts which reads ursula
