Installing docker on Ubuntu 22.04
All U-Query components run as docker containers. Follow these steps below to install docker.
1. Install required dependencies
sudo apt update
sudo apt install -y apt-transport-https ca-certificates curl software-properties-common
2. Add the docker GPG key and repository
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.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
3. Install docker
sudo apt install -y docker-ce docker-ce-cli containerd.io
4. Add your user to the docker group to run Docker commands without sudo
sudo usermod -aG docker $USER
newgrp docker
5. Test installation
Run the hello-world docker image to test the installation.
docker run hello-world
Example Output
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
