Docker: attach to a specific bash
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Lets say I have a container running and I do
docker exec -ti container-id /bin/bash
Then I detach from this container and want to attach again
If I do this
docker attach container-id
I wont go back to that bash that I created. Instead I will go to the main process.
How can I attach to that bash again ?

You can't. While the docker exec documentation suggests it supports the same "detach" key sequence as docker run, the exec'd process doesn't have any Docker-level identity (beyond its host and container pids) and there's no way to re-attach to that shell.
(In the Docker API, "exec instance" is an actual object so this isn't technically impossible; the CLI just has no support for it.)
The workflow you're describing sounds more like what you'd run with screen or tmux in a virtual machine.

I have one container and I have started it using, and checked the pid of /bin/bash
[root@ip-10-0-1-153 centos]# docker exec -ti 78c2e4a46b58 /bin/bash
root@78c2e4a46b58:/# ps -ef
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 03:24 ? 00:00:00 bash
root 10 0 0 03:24 ? 00:00:00 /bin/bash
root 20 10 0 03:24 ? 00:00:00 ps -ef
Now I detach from container using CTR+p and CTR+q sequence and container is detached.
Now I reattach using the container id and I see the same pid of /bin/bash
root@78c2e4a46b58:/# [root@ip-10-0-1-153 centos]# docker attach 78c2e4a46b58
root@78c2e4a46b58:/# ps -ef
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 03:24 ? 00:00:00 bash
root 10 0 0 03:24 ? 00:00:00 /bin/bash
root 21 1 0 03:25 ? 00:00:00 ps -ef
root@78c2e4a46b58:/#
I hope you're using CTR+p CTR+q sequence to detach from the container.

I have one container and I have started it using, and checked the pid of /bin/bash
[root@ip-10-0-1-153 centos]# docker exec -ti 78c2e4a46b58 /bin/bash
root@78c2e4a46b58:/# ps -ef
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 03:24 ? 00:00:00 bash
root 10 0 0 03:24 ? 00:00:00 /bin/bash
root 20 10 0 03:24 ? 00:00:00 ps -ef
Now I detach from container using CTR+p and CTR+q sequence and container is detached.
Now I reattach using the container id and I see the same pid of /bin/bash
root@78c2e4a46b58:/# [root@ip-10-0-1-153 centos]# docker attach 78c2e4a46b58
