VM setup
Setting up a cloud VM
Requirements
- A linux server with a public IP address.
I am using a Ubuntu 22.04 server with 1GB RAM and 1vCPU on Oracle Cloud.
Update the system
- Boot the VM & ssh into it.
- Update the system:
sudo apt update && sudo apt upgrade -y
Install docker
sudo apt remove docker docker-engine docker.io containerd run
sudo apt update
sudo apt install \
ca-certificates \
curl \
gnupg \
lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL <https://download.docker.com/linux/ubuntu/gpg> | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] <https://download.docker.com/linux/ubuntu> \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin
Add current user to docker group
- If you are not logged in as root, you will need to add your user to the docker group to run docker commands without sudo.
sudo usermod -aG docker $USER
Open ports for http & https
- This is Oracle Cloud specific as I am using it.
- Go to the VM’s home page.
- Find “Subnet” under “Primary VNIC” section and click on it
- Navigate to “Security Lists” > “Default Security List for VCN” > Add Ingress Rules button
- Source CIDR: 0.0.0.0/0, IP Protocol: TCP, Destination Port Range: 80, 443
- Click on “Add Ingress Rules” button
- This will open ports 80 & 443 to the internet
