[ubuntu] How to run wget inside Ubuntu Docker image?

I'm trying to download a Debian package inside a Ubuntu container as follows:

sudo docker run ubuntu:14.04 wget https://downloads-packages.s3.amazonaws.com/ubuntu-14.04/gitlab_7.8.2-omnibus.1-1_amd64.deb

I get

exec: "wget": executable file not found in $PATH

I've already installed wget with docker as follows:

run ubuntu:14.04 apt-get install wget

How can I download a file?

This question is related to ubuntu docker wget

The answer is


If you're running ubuntu container directly without a local Dockerfile you can ssh into the container and enable root control by entering su then apt-get install -y wget


I had this problem recently where apt install wget does not find anything. As it turns out apt update was never run.

apt update
apt install wget

After discussing this with a coworker we mused that apt update is likely not run in order to save both time and space in the docker image.
