Hi, I need something similar. I have a database server running on one of the containers and I have another container that fetches the data from the first container. So I need the two containers to be linked and connected.

Is this possible?
@Abhishek have a look at my answer. I am not very sure about your requirement. If this answer does not help, please give a detailed explanation of your requirements.

@Yuvraj, I hope your doubt is cleared.

Thank you!

Hi @Yuvraj! Yes, this is possible.

You can sue the link flag for this.
When you launch the second container, use a command similar to this:

$ docker run -it --link redis1:redis --name redisclient1 busybox

The value provided to the — link flag is sourcecontainername:containeraliasname. We have chosen the value redis1 in the sourcecontainername

The above launch of the container (redisclient1) will lead you to the shell prompt.
