# Local Installation & Running
16+
17+
Local installation on a Centos7 machine looks like:
18+
19+
sudo yum install -y gcc python3-pip python3-devel openssl-devel python3-libselinux
20+
sudo yum install -y docker-ce docker-ce-cli containerd.io
21+
sudo yum install -y yum-utils
22+
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
23+
sudo yum install -y docker-ce docker-ce-cli containerd.io
24+
python3 -m pip install --upgrade --user pip
25+
python3 -m pip install --upgrade --user setuptools
26+
python3 -m pip install --upgrade --user "molecule[lint]"
27+
python3 -m pip install --upgrade --user docker
28+
29+
sudo systemctl start docker
30+
sudo usermod -aG docker ${USER}
31+
newgrp docker
32+
docker run hello-world # test docker works without sudo
33+
34+
sudo yum install -y git
35+
git clone [email protected]:stackhpc/ansible-role-openhpc.git
36+
cd ansible-role-openhpc/
37+
38+
Then to run all tests:
39+
40+
cd ansible-role-openhpc/
41+
molecule test --all
