On-premise installation

For an on-premise installation you will need a server which can run docker and docker_compose. For windows servers, installation of docker_compose might be difficult see: https://docs.docker.com/compose/install/ (opens in a new tab) .

Prerequisites to Dessia’s platform installation

The user must have access to persistent Administrator rights on his computer in order to install docker engine and docker desktop on his computer
The user need to install WSL with the docker install
```
wsl --install
wsl --version
```

Deployment without internet connection

For deployment without an internet connection, follow these steps:

Step 1: Install Docker

1.1: Without Internet Connection
- Launch the Docker Desktop Installer: Docker Desktop Installer.exe.
- Ensure that the WSL installation is activated and install Docker with the recommended configuration.
- Verify the installation of both Docker Desktop and Docker using commands on the command line terminal.
```
docker
docker --version
```

Step 2: Load Images and Check Loading

Use the command line terminal to load the necessary images using the following commands. NB: Think about changing images names depending on the real image file names. For example, if backend file is named “dessia_backend_stable.tar”, change “backend.tar” for “dessia_backend_stable.tar”.
```
docker load -i backend.tar
docker load -i frontend.tar
docker load -i mariadb.tar
docker load -i mongo.tar
docker load -i pypiserver.tar
```
Check if all the required images are loaded using the following command in your terminal:
```
docker image ls
docker info
```
You may obtain such a result (image names, tags and ids are given as example here):
If at least one of these lines shows a <none> value (as illustrated below), follow the following process:
- Identify through the image names, the repository for which name and tag are missing. Copy in your clipboard the corresponding image id (in the example above, it’s: 8d197fdf5126)
- Enter the command below in your terminal with the following details:
  - image_id: Paste the image id identified above
  - new*name: Choose an easy name to identify the repository *(for example: backend or frontend, etc.)_
  - new*tag: Choose an easy tag to identify *(for example: version number or “latest”)_
```
docker tag "image_id" "new_name":"new_tag"
 
"As an example: docker tag 8d197fdf5126 dessia_backend:latest"
```
- Report the name and tag you’ve just entered in the corresponding repository in the docker-compose.yml file (as illustrated below for the example described above):
- Repeat the process for each repository concerned with the <none> value before continuing the installation.
- Check that everything is alright by entering once again the following command line in your terminal
```
docker image ls
```

Step 3: Copy to Deploy Folder

Copy the Docker Compose YML files and the my.cnf file to the designated deployment folder. Ensure this is not a temporary folder.

Step 4: Start Services

4.1: Without Internet Connection

Before executing the following command, ensure that the names and tags of the images you provided in the docker-compose.yml file match the names and tags of the images you have loaded.

docker image ls
REPOSITORY                             TAG                          IMAGE ID       CREATED         SIZE
dessia-platform-frontend               localhost_5000-v0.18.8       dbbbd3f196a2   22 hours ago    173MB
dessia_platform_front                  v0.18.8                      dbbbd3f196a2   22 hours ago    173MB

dessia_platform_back_end               v0.20.2                      1392942b1312   12 days ago     1.21GB

mongo                                  4                            af86910c16da   14 months ago   438MB
mariadb                                10.7                         159a32906318   14 months ago   415MB
mariadb                                latest                       7d424d763ecb   14 months ago   384MB

Run the deployment command without an internet connection using:

docker-compose -f docker-compose.yml -f docker-compose.no-network.yml up -d

Step 5: Put PyPi Packages (only without internet connection)

Copy all files from the 'pypi-packages' folder into the dedicated volume path: NB: Copy directly the files (not the folder containing the files) in the path
```
\\wsl$\docker-desktop-data\data\docker\volumes\*actual_folder_name_pypi-packages*\_data
```
Replace 'actual_folder_name_backend-packages' with the correct folder name ending with '_pypi-packages' (actual folder name is the same name with the directory where you put your docker images, docker_compose.yml …).

Step 6: Start the Platform, Create Your Account, and Load Dessia_Common

Start the global container and navigate to the frontend page.
Create your platform account. As the first user to create an account, you will automatically be assigned the Admin role.
Load your 'dessia_common' wheel file in ADMIN/Applications and restart the platform.
On the ADMIN page, verify if 'Dessia_Common' has a green illuminated button, indicating successful loading and activation.
Load all the other wheel files (one by one starting with volmdlr and plot_data) in the platform. Restart the platform for each step.

Troubleshooting

If encountering issues during deployment, consider the following troubleshooting steps:

Verify the installation steps for Docker, ensuring correct configuration and dependencies.
Check if all required images are properly loaded using the 'docker image ls' command.
Ensure that files are correctly copied to the deployment folder.
Verify the command used for starting services matches the intended configuration.
Confirm the correct path and placement of PyPi packages without internet connection.
Check for any error messages or logs provided by Docker or related commands
```
docker container ls
docker container logs container_id (container_name)
```
