Installation¶

Prerequisites¶

Follow the official Docker documentation for Ubuntu:

https://docs.docker.com/engine/install/ubuntu/

Then execute the following commands:

sudo umask 022

sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg

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

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

sudo apt-get update

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

You must authenticate once to download images from Docker Hub:

docker login --username <your-username>

Verify Installation¶

Run the following test container:

1	`docker run hello-world`

If everything is working properly, Docker should display a confirmation message.

Install OpenJTS¶

1. Create a Dedicated User¶

From the root account, create a dedicated user for OpenJTS:

adduser openjts
adduser openjts sudo

2. Switch to the New User¶

1	`su - openjts`

3. Clone the Repository¶

Create a working directory and clone the OpenJTS repository:

mkdir -p ~/JTS
cd ~/JTS

git clone https://github.com/door7302/openjts .

Note: The last dot "." is useful. Don't miss it.

4. Build the Stack¶

Navigate to the compose directory and build all containers:

cd compose
docker compose build --no-cache

The stack images will now be built locally. You are ready to proceed with the configuration phase.
