How much do I have to pay for a de.NBI Cloud project?¶
The de.NBI Cloud is fully funded by the federal ministry of education and research. It is free for all academic life science research projects.
I can not build docker images and can not download packages from inside of the container.¶
In case you use docker containers in your VM it may happen that the building process of the containers will fail or you can not download packages. The reason is that docker can not connect to the internet. The problem is caused by different mtu values for the host and the docker container. To fix the problem you have to add the correct mtu value to the following file:
Add --mtu=1440 to the end of the ExecStart line in the [Service] section, like shown below:
ExecStart=/usr/bin/docker daemon -H fd:// --mtu=1440
In a last step you have to reload the daemon and restart docker:
sudo systemctl daemon-reload sudo systemctl docker restart
Now the docker build process should be successful.
