building .net applications on a docker image

The pain is that you can't run a Windows docker image on Linux. And Microsoft images with the .net libraries are all Windows.
Like this one https://hub.docker.com/r/compulim/msbuild/

BUT you can build a ubuntu-based docker builder image:

it's available on docker hub as vernetto/ubuntudotnet:1.0

docker latest update fails miserably

sudo journalctl -xe

mkdir /run/containerd/io.containerd.runtime.v2.task/docker/dockerd: file exists: unknown


it seems a bug of the latest (nightly) release.... which was installed automatically by the Centos updates process.


I uninstall everything:

sudo yum remove docker docker-common docker-selinux docker-engine

Then I install

https://docs.docker.com/install/linux/docker-ce/centos/#set-up-the-repository

sudo yum-config-manager --disable docker-ce-edge

sudo yum install docker-ce
sudo systemctl enable docker
systemctl start docker

systemctl status docker.service

Error starting daemon: error initializing graphdriver: /var/lib/docker contains several valid graphdrivers: devicemapper, overlay2; Please cleanup or explicit

sudo vi /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd -s=devicemapper -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

sudo systemctl daemon-reload
sudo systemctl start docker

Nexus 3.10 as Python pypi proxy

sudo yum -y update
sudo yum -y install python-pip
pip --help
pip -V
mkdir ~/.pip
cd .pip/
vi pip.conf

enter this:

[global]
index = http://localhost:8181/repository/pypi/
index-url = http://localhost:8181/repository/pypi/simple

Create a nexus Pypi proxy repo "pypi" pointing to https://pypi.org/ . Leave all the defaults as they are.

pip install lino-amici

this should populate your nexus:

No worries about the message about the python version.... I have 2.7.... not willing to upgrade for now...
