Docker - Ubuntu - bash: ping: command not found
I've got a Docker container running Ubuntu which I did as follows:
docker run -it ubuntu /bin/bash
however it doesn't seem to have
bash: ping: command not found
Do I need to install that?
Seems a pretty basic command to be missing. I tried
whereis ping which doesn't report anything.
Docker images are pretty minimal, But you can install
ping in your official ubuntu docker image via:
apt-get update apt-get install iputils-ping
Chances are you dont need
ping your image, and just want to use it for testing purposes. Above example will help you out.
But if you need ping to exist on your image, you can create a
commit the container you ran the above commands in to a new image.
docker commit -m "Installed iputils-ping" --author "Your Name <firstname.lastname@example.org>" ContainerNameOrId yourrepository/imagename:tag
FROM ubuntu RUN apt-get update && apt-get install -y iputils-ping CMD bash
Please note there are best practices on creating docker images, Like clearing apt cache files after and etc.
