Pentaho Containers

The following steps are intended for setting up a Pentaho Lab environment and need to be completed in order to complete the Workshops.

Ensure you have downloaded the Workshop--Installation:

cd
git clone https://github.com/jporeilly/Workshop--Installation

To install git:

sudo apt install git

Docker

Docker

Docker is a platform that enables developers to package applications and their dependencies into lightweight, portable containers. Containers ensure that applications run consistently across different computing environments, from development laptops to production servers. This workshop will guide you through the complete process of installing Docker Engine on Ubuntu 24.04 LTS (Noble Numbat).

1. Before installing Docker, update your existing package list.

sudo apt update && sudo apt upgrade

1. Install packages that allow apt to use repositories over HTTPS.

sudo apt install -y ca-certificates curl gnupg lsb-release

1. Create a directory for keyrings and add Docker's GPG key.

sudo install -m 0755 -d /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

sudo chmod a+r /etc/apt/keyrings/docker.gpg

1. Add the Docker repository to your apt sources.

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

1. Now that the Docker repository is added, update the package index.

sudo apt update && sudo apt upgrade

1. Install Docker Engine, containerd, and Docker Compose.

sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

1. Check that Docker is installed correctly by checking the version.

docker --version

You should see output similar to (Nov 2025):

Docker version 29.0.2, build 810xxxx

1. Verify that Docker Engine is running.

sudo systemctl status docker

The service should show as "active (running)".

1. Quit.

q

1. Test your Docker installation by running the hello-world container.

sudo docker run hello-world

This command downloads a test image and runs it in a container. If successful, you'll see a message confirming that Docker is working correctly.

---

Without Sudo

By default, Docker requires sudo privileges. To run Docker commands without sudo.

1. Add your user to the docker group.

sudo usermod -aG docker $USER

1. Apply the new group membership (or log out and back in).

newgrp docker

1. Verify you can run Docker without sudo.

docker run hello-world

1. Ensure Docker starts automatically when the system boots.

sudo systemctl enable docker.service
sudo systemctl enable containerd.service

---

Verification & Testing

To confirm everything is working properly, run the following commands:

Check Docker version:

docker version

View Docker system information:

docker info

List running containers:

docker ps

List all containers (including stopped ones):

docker ps -a

List downloaded images:

docker images

---

Common Commands

Here are essential Docker commands you'll use regularly:

• docker pull <image> - Download an image from Docker Hub

• docker images - List all local images

• docker run <image> - Create and start a container from an image

• docker ps - List running containers

• docker ps -a - List all containers

• docker stop <container> - Stop a running container

• docker rm <container> - Remove a stopped container

• docker rmi <image> - Remove an image

• docker logs <container> - View container logs

• docker exec -it <container> bash - Access a running container's shell
