TerminusDB Server Container Control

This is a simple convenience script to run terminusdb-server as a docker container.

What the heck is TerminusDB? See here: https://terminusdb.com

Prerequisites

Docker

Since this script uses the TerminusDB Docker container, you need to have Docker running.

On Windows and Mac, Docker Desktop can be downloaded here: https://www.docker.com/products/docker-desktop

Note that on Windows, the default memory allowed for Docker is 2GB. Since this is an in-memory database, bigger databases require more memory. Therefore raise the default allowed memory usage to a higher value in the Docker Desktop settings.

On Linux, use your distro's package manager, or find more information here: https://www.docker.com/products/container-runtime

Git

This script is distributed via GitHub, so you will need git to clone and update it, if you don't already have git, you can download it here: https://git-scm.com/downloads

Windows users should use the application "Git Bash" for all terminal commands described below, this application comes with Git for Windows.

Sudo

Sudo is optional. As letting unprivileged users run docker is insecure, this script uses sudo by default if it is available.

Most users will not need to do anything here, sudo is installed by default on Macs and many populer Linux distros such as Fedora, Red Hat, Debian, Ubuntu and Mint. Linux users who use minmal distros such as Archlinux, are advised to install sudo and confugure their sudoers file accordingly.

Windows users do not need to do anything here.

Installing

Get this repo, cd to it

git clone https://github.com/terminusdb/terminusdb-bootstrap
cd terminusdb-bootstrap

Run the container by using the script (the first time)

./terminusdb-container run

Unable to find image 'terminusdb/terminusdb-server:latest' locally

If you've installed before

You may need to remove previous volumes or you may encounter bugs or the old console.

Warning: This will lead to losing local data.

 ./terminusdb-container rm

This will delete storage volume
Are you sure? [y/N] y

Using the console

Ready to terminate? Open the TerminusDB Console in your web browser.

./terminusdb-container console

Or go here: http://localhost:6363/

To stop, attach, etc, see usage

./terminusdb-container 

USAGE:
  terminusdb-container [COMMAND]

  help        show usage
  run         run container
  stop        stop container
  console     launch console in web browser
  attach      attach to prolog shell
  exec        execeute a command inside the container
  rm          remove volumes

That's it! You're ready to go!

Using The Enviroment

This script is designed to "work out of the box," however, there may be situations where advanced users want to override some of it's defaults, this is done by setting enviroment variables.

Security

TerminusDB Bootstrap has HTTPS turned off by default to avoid scary security warnings since it's impossible to responsibly provide a valid SSL certificate for localhost.

To prevent accidental insecure deployments, the Docker container binds to the IP 127.0.0.1 and therefore the server will only be accessible on the local machine, and not from any other machine over the network.

If you would like to deploy to a server, you will need to enable HTTPS, and then accept the browser security warning about the self signed cert.

You can enable HTTPS with the TERMINUSDB_HTTPS_ENABLED environment variable.

TERMINUSDB_HTTPS_ENABLED=true ./terminusdb-container run

This will work out of the box using the self-signed cert that ships with TerminusDB Server. However, this certificate will require that you accept the certificate as it is considered insecure by your browser.

To eliminate the browser security warning so that you do not need to accept the certificate, simply provide a valid certificate and set the path to the cert and key with environment variables like in this example:

TERMINUSDB_HTTPS_ENABLED=true
TERMINUSDB_SSL_CERT=/etc/letsencrypt/live/example.com/fullchain.pem
TERMINUSDB_SSL_CERT_KEY=/etc/letsencrypt/live/example.com/privkey.pem

To make your server available across the network you will also need to set TERMINUSDB_AUTOLOGIN to false

TERMINUSDB_AUTOLOGIN=false

ENV File

The script sources a file called ENV if it is found in the current directory. See ENV.example for examples of the environment variables that can be set.

To have environment variables set every time you run ./terminusdb-container, follow these steps:

1. Copy ENV.example to ENV.
2. Edit ENV: uncomment the lines you want to change and set the values.

ENV reference

ENV name	Default value	Purpose
TERMINUSDB_DOCKER	sudo docker	Default docker command
TERMINUSDB_CONTAINER	terminusdb-server	Name of the running container
TERMINUSDB_REPOSITORY	terminusdb/terminusdb-server	Docker image
TERMINUSDB_NETWORK	bridge	Docker network mode
TERMINUSDB_TAG	The latest version tag of terminusdb-server	TerminusDB docker image version
TERMINUSDB_STORAGE	terminusdb_storage_local	Storage volume name
TERMINUSDB_PORT	6363	Port to run TerminusDB
TERMINUSDB_LOCAL		Local folder to mount inside container
TERMINUSDB_SERVER	127.0.0.1	Server on which TerminusDB will run
TERMINUSDB_PASS	root	Password for accessing TerminusDB
TERMINUSDB_AUTOLOGIN	false	Whether the administration console should automatically login
TERMINUSDB_CONSOLE	http://127.0.0.1/console	URL for browser top open console
TERMINUSDB_CONSOLE_BASE_URL	https://unpkg.com/@terminusdb/terminusdb-console@SOME_VERSION/console/dist/	URL to hosted console
TERMINUSDB_HTTPS_ENABLED	false	Enable HTTPS
TERMINUSDB_SSL_CERT	A self signed cert	Path to SSL cert inside terminusdb-server container
TERMINUSDB_SSL_CERT_KEY	A self-created private key	Path to private key for SSL cert inside container

Examples

These are examples of environment variables you can set when running ./terminusdb-container.

Mount a local directory inside the container

TERMINUSDB_LOCAL=/path/to/dir ./terminusdb-container [COMMAND]

Set the Docker Volume name

TERMINUSDB_STORAGE=terminus_storage_local ./terminusdb-container [COMMAND]

Using the latest release

TERMINUSDB_TAG=latest ./terminusdb-container [COMMAND]

Using the development release

TERMINUSDB_TAG=dev ./terminusdb-container [COMMAND]

Using a specific release instead of latest realease

TERMINUSDB_TAG=v1.1.2 ./terminusdb-container [COMMAND]

Using a local version of TerminusDB Console instead of the published version

TERMINUSDB_CONSOLE_BASE_URL=//127.0.0.1:3005 ./terminusdb-container [COMMAND]

Not using sudo even when sudo is available

TERMINUSDB_DOCKER=docker ./terminusdb-container [COMMAND]

Using podman instead of docker command

TERMINUSDB_DOCKER="podman" ./terminusdb-container [COMMAND]

See the source code to find the other environment variables that can be set.
