bash: line : docker: command not found

I am using jenkins in a docker container and would like to start another instance, whenever I try to use docker command like

docker run -t -i ap/dashboard /bin/bash

I get this error:

bash: line 61: docker: command not found

How do I navigate to another container or solve this error?

I can clearly see that the vm creator was able to use the docker command by reading the /root/.ash_history

here are some details about the system:

Looks like we're in a Docker container: 10:net_prio:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 9:net_cls:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 8:freezer:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 7:devices:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 6:memory:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 5:blkio:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 4:cpuacct:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 3:cpu:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 2:cpuset:/docker/b51cdbb7eebd806431ee4120d9b3ae050dbefe4a835bf2063446724572e45e30 1:name=openrc:/docker -rwxr-xr-x 1 root root 0 May 16 2016 /.dockerenv


[-] Anything juicy in the Dockerfile:
-rw-r--r--    1 root     root           617 May 12  2016 /root/dockerfiles/jenkins/Dockerfile

I tried many docker commands without hope

is it because that I'm already inside the container??

Try with docker run -t -i ap/dashboard /bin/ash.

Maybe your container does not use bash so you should try with /bin/sh which is a symcolic link to the default installed shell processor.
