One day, I am working on creating a docker image for a customized ROS package. In the Dockerfile, I wrote the apt-get command
to do the update and install the required ROS packages such as rosbridge-server and rospy-message-converter. However, during
the docker build process, I encountered the following errors:

I tried to find a solution and I found a good one which is configuring the DNS for our docker. You can configure the DNS in
/etc/docker/daemon.json file. In my case, since I was using Indihome from Magelang, the closest DNS would be Indihome DNS
in Semarang. So, I configure the dns to 203.130.208.18.

#/etc/docker/daemon.json
{
"dns": ["203.130.208.18"]
}

Don’t forget to restart the docker service.

sudo service docker restart

Once it has been configured, the build process going smoothly and I can use apt-get command inside the docker.
