ViSUS Docker Deployment

Jump to: navigation, search

Quick start

Start your Docker and login into your account. If you don't have installed follow these instructions: Docker Documentation

To log in from your terminal:

docker login
Username: your_username
Password: XXXX

Now pull the ViSUS image:

docker pull visus/visus

This image contains:

Run the image:

docker run -it --rm -p 8080:80 visus/visus

Check if the server is running:

curl -v "http://localhost:8080/mod_visus?action=list"

You will get a list of the current datasets on the server.

Content of the image

This image contains folders with configuration files and utilities. The folders of interest are under /home/visus:

  • config, it contains the visus server.config (see ViSUS configuration file)
  • apache2, it contains the apache2 config files that you can use for security settings (see ViSUS Server)
  • visus, it contains visus tool (see ViSUS Convert) to convert data to IDX format

The user can map those folders locally and edit them adding:

-v local_directory:docker_directory

when you run you docker image.

For example if you want to use your own ViSUS configuration file you can run the container as following:

docker run -d -p 8080:80 -v $PWD/config:/home/visus/config

Note: The server needs to be able to read and write the configuration file, so make sure that your server.config has the right privileges. For example:

chmod 766 /path/to/your/server.config

Making the configuration file writable will allow to add datasets dynamically using the action add_dataset (see ViSUS Server).

If you also want to customize the apache security (e.g. change the users) you can run the command to mount also the apache2 directory as following:

docker run -d -p 8080:80 -v $PWD/config:/home/visus/config -v $PWD/apache2:/home/visus/apache2 visus/visus

Use ViSUS convert from the Docker container

The ViSUS tools executables (see ViSUS Convert) are contained in the image under /usr/local/visus/bin.

For example, if you want to use the tools to convert a raw dataset using your docker deployment you can do it as follow.

Mount a folder that contains your raw data and your converted idx data as follow:

docker run -d -p 8080:80 -v /full/path/to/your/raw/:/home/visus/datasets/raw -v /full/path/to/your/idx/:/home/visus/datasets/idx visus/visus

Check that your container is running correctly (using docker ps) and take note of the Container ID.

Now run a bash session on this container using:

docker exec -it <id_from_docker_ps> /bin/bash

From this bash session you can use your ViSUS converter to convert your data (just mounted in the container) as described in ViSUS Convert.

Experimental: Web Viewer

You can preview and navigate you data on the server using the webviewer using your browser at the URL: http://localhost:8080

Here is a picture of the viewer: 2dwebviewer.png

With the commands on the bottom bar you can:

  • change server
  • set a slice (if using a 3D dataset)
  • set a timestep
  • set palettes and min-max range
  • choose a field of the selected dataset

Note: this component is experimental and under development.
