Installation on your Server
The easiest way to get started with webKnossos is to get an account on webKnossso.org.
webKnossos is open-source, so you can install it on your own server. We recommend a server with at least 4 CPU cores, 16 GB RAM, and as much disk space as you require for your datasets.
This tutorial shows how to install webKnossos on a fresh VM, which is available over the public internet and has a domain name (or a subdomain) already configured. webKnossos will then be available over a secured connection (HTTPS) with automatic certificate management.
# Create a new folder for webknossos mkdir -p /opt/webknossos cd /opt/webknossos # Download the docker-compose.yml for hosting wget https://github.com/scalableminds/webknossos/raw/master/tools/hosting/docker-compose.yml # Create the binaryData folder which will contain all your datasets mkdir binaryData # The binaryData folder needs to be readable/writable by user id=1000,gid=1000 chown -R 1000:1000 binaryData # Start webKnossos and supply the DOCKER_TAG, PUBLIC_HOST and LETSENCRYPT_EMAIL variables # In addition to webKnossos, we also start an nginx proxy with automatic # SSL certificate management via letsencrypt # Note that PUBLIC_HOST does not include http:// or https:// prefixes # Please look up the latest webKnossos version number at https://github.com/scalableminds/webknossos/releases DOCKER_TAG=xx.yy.z PUBLIC_HOST=webknossos.example.com LETSENCRYPT_EMAILemail@example.com \ docker-compose up webknossos nginx nginx-letsencrypt # Wait a couple of minutes for webKnossos to become available under your domain # e.g. https://webknossos.example.com # Set up your organization and admin account using the onboarding screens (see below) # After the initial run, you can start webKnossos in the background DOCKER_TAG=xx.yy.z PUBLIC_HOST=webknossos.example.com LETSENCRYPT_EMAILfirstname.lastname@example.org \ docker-compose up -d webknossos nginx nginx-letsencrypt # Congratulations! Your webKnossos is now up and running. # Stop everything docker-compose down
This setup does not support regular backups or monitoring. Please check out our paid service plans if you require any assistance with your production setup.
For installations on localhost, please refer to the Readme.
When starting with webKnossos you first need to create an organization. An organization represents your lab in webKnossos and handles permissions for users and datasets. Choose a descriptive name for your organization, e.g., "The University of Springfield", "Simpsons Lab" or "Neuroscience Department".
In the onboarding flow, you are asked to create a user account for yourself. This will be the first user of your organization which will automatically be activated and granted admin rights. Make sure to enter a correct email address.
Your First Dataset
Without any data, webKnossos is not fun. Luckily, there are some sample datasets that you can download directly from the onboarding screens. Once you've completed the onboarding, you can also import your own datasets.
For small datasets (max. 1GB), you can use the upload functionality provided in the web interface. For larger datasets, we recommend the file system upload. Read more about the import functionality in the Datasets guide.
By default, datasets are visible to all users in your organization. However, webKnossos includes fine-grained permissions to assign datasets to groups of users.
