jafner/5etools-docker Docker 镜像 - 轩辕镜像

This is a simple image for hosting your own 5eTools instance. It is based on the Apache httpd image and uses components of the auto-updater script from the 5eTools wiki. This image is built from this GitHub repository.

Usage

Below we talk about how to install and configure the container.

Default Configuration

You can quick-start this image by running:

mkdir -p ~/5etools-docker/htdocs && cd ~/5etools-docker
curl -o docker-compose.yml [***]
docker-compose up -d && docker logs -f 5etools-docker

Then give the container a few minutes to come online (it takes a while to pull the Github repository) and it will be accessible at localhost:8080. When you stop the container, it will automatically delete itself. The downloaded files will remain in the ~/5etools-docker/htdocs directory, so you can always start the container back up by running docker-compose up -d.

Volume Mapping

By default, I assume you want to keep downloaded files, even if the container dies. And you want the downloaded files to be located at ~/5etools-docker/htdocs.

If you want the files to be located somewhere else on your system, change the left side of the volume mapping. For example, if I wanted to keep my files at ~/data/docker/5etools, the volume mapping would be:

    volumes:
      - ~/data/docker/5etools:/usr/local/apache2/htdocs

Alternatively, you can have Docker or Compose manage your volume. (This makes adding homebrew practically impossible.)

Use a Compose-managed volume with:

...
    volumes:
      - 5etools-docker:/usr/local/apache2/htdocs
...
volumes:
  5etools-docker:

Or have the Docker engine manage the volume (as opposed to Compose). First, create the volume with docker volume create 5etools-docker, then add the following to your docker-compose.yml:

...
    volumes:
      - 5etools-docker:/usr/local/apache2/htdocs
...
volumes:
  5etools-docker:
    external: true

Environment Variables

The image uses environment variables to figure out how you want it to run. By default, I assume you want to automatically download the latest files from the Github mirror. Use the environment variables in the docker-compose.yml file to configure things.

IMG (defaults to FALSE)

Required unless OFFLINE_MODE=TRUE. Expects one of "TRUE", "FALSE" Where:

"TRUE" pulls from [] and adds [] as a submodule for image files. "FALSE" pulls from [***] without image files.

The get.5e.tools source has been down (redirecting to 5e.tools) during development. This method is not tested.

OFFLINE_MODE

Optional. Expects "TRUE" to enable. Setting this to true tells the server to run from the local files if available, or exits if there is no local version.

PUID and PGID

During the image build process, we set the owner of the htdocs directory to 1000:1000 by default. If you need a different UID and GID to own the files, you can build the image from the source Dockerfile and pass the PUID and PGID variables as desired.

Integrating a reverse proxy

Supporting integration of a reverse proxy is beyond the scope of this guide. However, any instructions which work for the base httpd (Apache) image, should also work for this, as it is minimally different.

Auto-loading homebrew

To use auto-loading homebrew, you will need to use a host directory mapping as described above.

1. Online the container and wait for the container to finish starting. You can monitor its progress with docker logs -f 5etools-docker.
2. Assuming you are using the mapping ~/5etools-docker/htdocs:/usr/local/apache2/htdocs place your homebrew json files into the ~/5etools-docker/htdocs/homebrew/ folder, then add their filenames to the ~/5etools-docker/htdocs/homebrew/index.json file. For example, if your homebrew folder contains:

index.json
'Jafner; JafnerBrew Campaigns.json'
'Jafner; JafnerBrew Collection.json'
'Jafner; Legendary Tomes of Knowledge.json'
'KibblesTasty; Artificer (Revised).json'

Then your index.json should look like:

json
{
    "readme": [
        "NOTE: This feature is designed for use in user-hosted copies of the site, and not for integrating \"official\" 5etools content.",
        "The \"production\" version of the site (i.e., not the development ZIP) has this feature disabled. You can re-enable it by replacing `IS_DEPLOYED = \"X.Y.Z\";` in the file `js/utils.js`, with `IS_DEPLOYED = undefined;`",
        "This file contains as an index for other homebrew files, which should be placed in the same directory.",
        "For example, add \"My Homebrew.json\" to the \"toImport\" array below, and have a valid JSON homebrew file in this (\"homebrew/\") directory."
    ],
    "toImport": [
        "Jafner; JafnerBrew Collection.json",
        "Jafner; JafnerBrew Campaigns.json",
        "Jafner; Legendary Tomes of Knowledge.json",
        "KibblesTasty; Artificer (Revised).json"
    ]
}

Note the commas after each entry except the last in each array. See the wiki page for more information.
