Requirements

1. Install Docker. See https://docs.docker.com/install/ for help. For lazy and

non-security minded Linux users, simply run the following command:
`curl -fsSL get.docker.com | sudo bash`

1. If you want to automatically start TiddlyWiki on boot, you will need to be

running a recent Linux distribution that uses systemd. (Ubuntu 12 or older,
for example, do not support systemd by default).

Manual Execution

$ docker run -p 8080:8080 --name mywiki nicolaw/tiddlywiki

Open your browser to http://localhost:8080 to access the TiddlyWiki.
Alternatively the following will instruct Docker to keep your TiddlyWiki container running at all times untill explicitly stopped with a docker stop or docker kill command:

$ mkdir ~/tiddlywiki
$ docker run \
    -p 8080:8080 -d --restart unless-stopped --name mywiki \
    -v ~/tiddlywiki:/var/lib/tiddlywiki \
    nicolaw/tiddlywiki

Systemd Service

A systemd service unit file is included in the source repository of this project. (See https://gitlab.com/nicolaw/tiddlywiki). This can be installed to automatically start one or more TiddlyWikis every time your machine boots.
It also provides you with some level of configurability by simply changing the contents of the /etc/tiddlywiki/mywiki.conf configuration file.

$ sudo mkdir /etc/tiddlywiki/
$ sudo cp tiddlywiki.service /etc/systemd/system/mywiki.service
$ sudo cp tiddlywiki.conf /etc/tiddlywiki/mywiki.conf
$ sudo systemctl daemon-reload
$ sudo systemctl start mywiki.service

Check the status of the TiddlyWiki service, or watch the logs using the following commands:

$ sudo systemctl status mywiki.service
$ sudo journalctl -f -u mywiki.service

Tiddler Data Storage

The container stores the Tiddler data in /var/lib/tiddlywiki. This will automatically be saved inside an anonymous Docker volume.
Specifying a volume bind mount location for /var/lib/tiddlywiki will cause the Tiddler data to be written to that location on your local filesystem.

$ docker run --rm -p 8080:8080 -v ~/wikidata:/var/lib/tiddlywiki --name mywiki nicolaw/tiddlywiki

In the case of operating TiddlyWiki from systemd, the Docker volume has the same name as the systemd service name (mywiki.service by default). Use docker volume inspect mywiki.service see where your data is being stored on disk in the event that you wish to perform a backup.
Alternatively, to specify a bind mount location, uncomment and modify the TW_DOCKERVOLUME line, and optionally the TW_DOCKERUID and TW_DOCKERGID lines in the /etc/tiddlywiki/mywiki.conf configuration file.
You will need to restart the service once you have saved your file change.

$ sudo vi /etc/tiddlywiki/mywiki.conf
$ sudo systemctl restart mywiki.service

Authentication

By default, the username is set to anonymous with no password.
Specify the TW_USERNAME and TW_PASSWORD environment variables to enable password authentication.

$ docker run -p 8080:8080 -e "TW_USERNAME=$USER" -e "TW_PASSWORD=hunter2" --name mywiki nicolaw/tiddlywiki

Similarly if you are using systemd to start your TiddlyWiki, uncomment and modify the TW_USERNAME and TW_PASSWORD lines from the /etc/tiddlywiki/mywiki.conf file.
You will need to restart the service once you have saved your file change.

$ sudo vi /etc/tiddlywiki/mywiki.conf
$ sudo systemctl restart mywiki.service

Configurable Variables

Refer to the canonical online documentation for help for additional help.

• https://tiddlywiki.com/static/Using%2520TiddlyWiki%2520on%2520Node.js.html
• https://tiddlywiki.com/static/ServerCommand.html

TW_WIKINAME=mywiki
TW_USERNAME=janedoe
TW_PASSWORD=
TW_PORT=8080
TW_ROOTTIDDLER=$:/core/save/all
TW_RENDERTYPE=text/plain
TW_SERVETYPE=text/html
TW_HOST=0.0.0.0
TW_PATHPREFIX=

You can alter how the NodeJS tiddlywiki server will operate by changing these two variables.
If you are operating in a low memory environment (inside a small AWS, GCE or other cloud virtual machine for example), you may wish to set NODE_MEM to specify the maximum memory can NodeJS may use (specified in MB).

NODE_MEM=400
NODE_OPTIONS=

The following variables only affect the operation while using the system service unit to start TiddlyWiki. They do nothing if you are running the Docker container independently of systemd.

TW_DOCKERVOLUME=/home/janedoe/tiddlywiki
TW_DOCKERUID=0
TW_DOCKERGID=0

Docker Compose

More experienced users may wish to use docker-compose to dynamically build a customised container image using the Git source repostiory as the build context. This allows control over the following Dockerfile build arguments:

• TW_VERSION - The upstream version of TiddlyWiki to install from NPM

(https://www.npmjs.com/package/tiddlywiki)

• BASE_IMAGE - The Docker base container image to inherit from (should

contain the node interpreter)

• USER - Unix user or UID to run the TiddlyWiki process as (useful if

your container runtime environment does not allow you to override)
The Makefile in the https://gitlab.com/nicolaw/tiddlywiki.git also makes use of these build arguments in a similar way.
Example partial Docker compose definition:

tiddlywiki:
  container_name: tiddlywiki
  image: nicolaw/tiddlywiki
  build:
    context: https://gitlab.com/nicolaw/tiddlywiki.git
    args:
      TW_VERSION: 5.2.2
      USER: 501
      BASE_IMAGE: 17.9-alpine3.15
````

To use the provided https://gitlab.com/nicolaw/tiddlywiki/-/blob/master/docker-compose.yaml:

```console
$ docker-compose up -d
Starting tiddlywiki ... done

Packer AWS AMIs

A Packer HCL definition https://gitlab.com/nicolaw/tiddlywiki/-/blob/master/docker-compose.yaml provides an easy mechanism to build an AWS EC2 AMI.

$ packer init .
$ packer build .

Public AWS AMIs are made available from the under the owner accound ID 172306058616 in the eu-west-2 EU London region.

$ aws ec2 describe-images \
  --region eu-west-2 --owners 172306058616 \
  --filters 'Name=name,Values=tiddlywiki-*' 'Name=architecture,Values=x86_64' \
  --query 'sort_by(Images, &CreationDate)[-1].ImageId' --output text
ami-00e143acd635f8693

This TiddlyWiki AMI will listen on port 80 by default for greater convenience.
Tiddler data is stored in a bind mount under /home/ec2-user/tiddlywiki by default.
Refer to the configuration variables documentation above to modify these settings in the /etc/tiddlywiki/tiddlywiki.conf configuration file. The TiddlyWiki service may be restarted using Systemd:

$ systemctl restart tiddlywiki.service
