"unzip: short read" error during container startup

foundryvtt-docker

You can get a Foundry Virtual Tabletop instance up and running in minutes using this container. This Docker container is designed to be secure, reliable, compact, and simple to use. It only requires that you provide the credentials or URL needed to download a Foundry Virtual Tabletop distribution.

Prerequisites

A functioning Docker installation.
A FoundryVTT.com account with a purchased software license.

Running

Running with Docker and credentials

You can use the following command to start up a Foundry Virtual Tabletop server. Your foundryvtt.com credentials are required so the container can install and license your server.

docker run \
  --env FOUNDRY_USERNAME='<your_username>' \
  --env FOUNDRY_PASSWORD='<your_password>' \
  --publish 30000:30000/tcp \
  --volume <your_data_dir>:/data \
  felddy/foundryvtt:release

Note

If you are using bash, or a similar shell, consider pre-pending the Docker command with a space to prevent your credentials from being committed to the shell history list. See: HISTCONTROL

Running with Docker and a temporary URL

Alternatively, you may acquire a temporary download URL from your user profile page on the Foundry website.

Navigate to the Purchased Software Licenses page.
Change the Operating System menu item to Linux/NodeJS.
Click the 🔗 Timed URL button to obtain the temporary URL.
Use the following command to start up a Foundry Virtual Tabletop server:

docker run \
  --env FOUNDRY_RELEASE_URL='<temporary_url>' \
  --publish 30000:30000/tcp \
  --volume <your_data_dir>:/data \
  felddy/foundryvtt:release

Configuration management

Configuration options are specified using environment variables. It is highly recommended that you use docker compose or similar container orchestration to manage your server's configuration. A docker-compose.yml file, like the example below, is a reliable way to start and maintain a container while capturing its configurations.

Each time the container starts it generates the configuration files needed by Foundry Virtual Tabletop using the values of the environment variables. That means changes made in the server's configuration GUI will not persist between container restarts. If you would like to disable the regeneration of these configuration files, set CONTAINER_PRESERVE_CONFIG to true.

Create a docker-compose.yml file similar to the one below. Provide your credentials as values to the environment variables:

---
version: "3.8"

services:
  foundry:
    image: felddy/foundryvtt:release
    hostname: my_foundry_host
    volumes:
      - type: bind
        source: <your_data_dir>
        target: /data
    environment:
      - FOUNDRY_PASSWORD=<your_password>
      - FOUNDRY_USERNAME=<your_username>
      - FOUNDRY_ADMIN_KEY=atropos
    ports:
      - target: 30000
        published: 30000
        protocol: tcp

Start the container and detach:
```
docker compose up --detach
```
Access the web application at: http://localhost:30000.

If all goes well you should be prompted with the license agreement, and then "admin access key" set with the FOUNDRY_ADMIN_KEY variable.

Using secrets

This container also supports passing sensitive values via Docker secrets. Passing sensitive values like your credentials can be more secure using secrets than using environment variables. Your secrets json file can have any name. This example uses secrets.json. Regardless of the name you choose it must be targeted to config.json within the container as in the example below. See the secrets section below for a table of all supported secret keys.

To use secrets, create a secrets.json file containing the values you want set:

{
  "foundry_admin_key": "atropos",
  "foundry_password": "your_password",
  "foundry_username": "your_username"
}

Then add the secret to your docker-compose.yml file:

---
version: "3.8"

secrets:
  config_json:
    file: secrets.json

services:
  foundry:
    image: felddy/foundryvtt:release
    hostname: my_foundry_host
    volumes:
      - type: bind
        source: <your_data_dir>
        target: /data
    environment:
    ports:
      - target: 30000
        published: 30000
        protocol: tcp
    secrets:
      - source: config_json
        target: config.json

Updating your container

The Foundry "Update Software" tab is disabled by default in this container. To upgrade to a new version of Foundry pull an updated image version.

Updating with Docker Compose

Pull the new image from Docker Hub:
```
docker compose pull
```
Recreate the running container:
```
docker compose up --detach
```

Updating with Docker

Stop the running container:
```
docker stop <container_id>
```
Pull the new image:
```
docker pull felddy/foundryvtt:release
```
Follow the previous instructions for running the container above.

Image tags

The images of this container are tagged with semantic versions that align with the version and build of Foundry Virtual Tabletop that they support. It is recommended that most users use the :release tag.

Image:tag	Description
`felddy/foundryvtt:release`	The most recent image from the `stable` channel. These images are considered stable, and well-tested. Most users will use this tag. The `latest` tag always points to the same version as `release`.
`felddy/foundryvtt:11.315.1`	An exact image version.
`felddy/foundryvtt:11.315`	The most recent image matching the major and minor version numbers.
`felddy/foundryvtt:11`	The most recent image matching the major version number.
`felddy/foundryvtt:latest`	See the `release` tag. Why does `latest` == `release`?

See the tags tab on Docker Hub for a list of all the supported tags.

Volumes

Mount point	Purpose
`/data`	Configuration, data, and log storage.

Ports

The following ports are exposed by this container:

Port	Purpose
`30000`	Foundry Virtual Tabletop server web interface

Environment variables

Required variable combinations

One of the three combinations of environment variables listed below must be set in order for the container to locate and install a Foundry Virtual Tabletop distribution. Although all variables may be specified together, they are evaluated in the following order of precedence:

FOUNDRY_RELEASE_URL, or
FOUNDRY_USERNAME and FOUNDRY_PASSWORD, or
CONTAINER_CACHE

Credentials variables

Name	Purpose
`FOUNDRY_PASSWORD`	Account password for foundryvtt.com. Required for downloading an application distribution.
`FOUNDRY_USERNAME`	Account username or email address for foundryvtt.com. Required for downloading an application distribution.

Note: FOUNDRY_USERNAME and FOUNDRY_PASSWORD may be set using secrets instead of environment variables.

Pre-signed URL variable

Name	Purpose
`FOUNDRY_RELEASE_URL`	S3 pre-signed URL generate from the user's profile. Required for downloading an application distribution.

Optional variables

Name	Purpose	Default
`CONTAINER_CACHE`	Set a path to cache downloads of the Foundry distribution archive and speed up subsequent container startups. The path should be in `/data` or another persistent mount point in the container. Set to `""` to disable. Note: When the cache is disabled the container may sleep instead of exiting, in certain circumstances, to prevent a download loop. A distribution can be pre-downloaded and placed into a cache directory. The distribution's name must be of the form: `foundryvtt-11.315.zip`	`/data/container_cache`
`CONTAINER_CACHE_SIZE`	Set the maximum number of distribution versions to keep in the cache. The minimum is `1`. When the limit is exceeded, the oldest versions (lowest version numbers) are removed first. Unset to disable cache size management and keep all versions.
`CONTAINER_PATCHES`	Set a path to a directory of shell scripts to be sourced after Foundry is installed but before it is started. The path should be in `/data` or another persistent mount point in the container. e.g.; `/data/container_patches` Patch files are sourced in lexicographic order. `CONTAINER_PATCHES` are processed after `CONTAINER_PATCH_URLS`.
`CONTAINER_PATCH_URLS`	Set to a space-delimited list of URLs to be sourced after Foundry is installed but before it is started. Patch URLs are sourced in the order specified. `CONTAINER_PATCH_URLS` are processed before `CONTAINER_PATCHES`. ⚠️ Only use patch URLs from trusted sources!
`CONTAINER_PRESERVE_CONFIG`	Normally new `options.json` and `admin.txt` files are generated by the container at each startup. Setting this to `true` prevents the container from modifying these files when they exist. If they do not exist, they will be created as normal.	`false`
`CONTAINER_PRESERVE_OWNER`	Normally the ownership of the `/data` directory and its contents are changed to match that of the server at startup. Setting this to a regular expression will exclude any matching paths and preserve their ownership. Note: This is a match on the whole path, not a search. This is useful if you want mount a volume as read-only inside `/data` (e.g.; a volume that contains assets mounted at `/data/Data/assets`).
`CONTAINER_URL_FETCH_RETRY`	Number of times to retry fetching the S3 pre-signed URL using exponential back off. This behavior is useful in continuous integration environments where multiple parallel workflows can exceed the rate-limit of the URL generation service.	`0`
`CONTAINER_VERBOSE`	Set to `true` to enable verbose logging for the container utility scripts.	`false`
`FOUNDRY_ADMIN_KEY`	Admin password to be applied at startup. If omitted the admin password will be cleared. May be set using secrets.
`FOUNDRY_AWS_CONFIG`	An absolute or relative path that points to the awsConfig.json or `true` for AWS environment variable credentials evaluation usage.	`null`
`FOUNDRY_COMPRESS_WEBSOCKET`	Set to `true` to enable compression of data sent from the server to the client via websocket. This is recommended for network performance.	`true`
`FOUNDRY_CSS_THEME`	Choose the CSS theme for the setup page. Choose from `foundry`, `fantasy`, or `scifi`.	`foundry`
`FOUNDRY_DEMO_CONFIG`	Demo mode allows you to configure a world which will be automatically launched and reset at a frequency of your choosing. When the world is reset, it is deactivated. The source data for the world is restored to its original state using a provided `.zip` file, and the next reset is automatically scheduled. See: Configuring demo mode.
`FOUNDRY_GID`	`gid` the daemon will be run under.	`foundry`
`FOUNDRY_HOSTNAME`	A custom hostname to use in place of the host machine's public IP address when displaying the address of the game session. This allows for reverse proxies or DNS servers to modify the public address.	`null`
`FOUNDRY_HOT_RELOAD`	Set to `true` to allow packages to hot-reload certain assets, such as CSS, HTML, and localization files without a full refresh. This setting is only recommended for developers.	`false`
`FOUNDRY_IP_DISCOVERY`	Allow the Foundry server to discover and report the accessibility of the host machine's public IP address and port. Setting this to `false` may reduce server startup time in instances where this discovery would timeout.	`true`
`FOUNDRY_LANGUAGE`	The default application language and module which provides the core translation files.	`en.core`
`FOUNDRY_LOCAL_HOSTNAME`	Override the local network address used for invitation links, mirroring the functionality of the `FOUNDRY_HOSTNAME` option which configures the external address.	`null`
`FOUNDRY_LICENSE_KEY`	The license key to install. e.g.; `AAAA-BBBB-CCCC-DDDD-EEEE-FFFF` If left unset, a license key will be fetched when using account authentication. If multiple license keys are associated with an account, one will be chosen at random. Specific licenses can be selected by passing in an integer index. The first license key being `1`. May be set using secrets.
`FOUNDRY_MINIFY_STATIC_FILES`	Set to `true` to reduce network traffic by serving minified static JavaScript and CSS files. Enabling this setting is recommended for most users, but module developers may wish to disable it.	`false`
`FOUNDRY_PASSWORD_SALT`	Custom salt string to be applied to the admin password instead of the default salt string. May be set using secrets.	`null`
`FOUNDRY_PROTOCOL`	If left unset Foundry VTT will bind to IPv4 and IPv6 interfaces. To limit to IPv4 only, set to `4`. To limit to IPv6 only set to `6`.	`null`
`FOUNDRY_PROXY_PORT`	Inform the Foundry server that the software is running behind a reverse proxy on some other port. This allows the invitation links created to the game to include the correct external port.	`null`
`FOUNDRY_PROXY_SSL`	Indicates whether the software is running behind a reverse proxy that uses SSL. This allows invitation links and A/V functionality to work as if the Foundry server had SSL configured directly.	`false`
`FOUNDRY_ROUTE_PREFIX`	A string path which is appended to the base hostname to serve Foundry VTT content from a specific namespace. For example setting this to `demo` will result in data being served from `http://x.x.x.x:30000/demo/`.	`null`
`FOUNDRY_SSL_CERT`	An absolute or relative path that points towards a SSL certificate file which is used jointly with the sslKey option to enable SSL and https connections. If both options are provided, the server will start using HTTPS automatically.	`null`
`FOUNDRY_SSL_KEY`	An absolute or relative path that points towards a SSL key file which is used jointly with the sslCert option to enable SSL and https connections. If both options are provided, the server will start using HTTPS automatically.	`null`
`FOUNDRY_TELEMETRY`	Set to `true` to enable FoundryVTT telemetry, `false` to disable. This options allows the collection of anonymous usage data to help improve FoundryVTT.	`null`
`FOUNDRY_UID`	`uid` the daemon will be run under.	`foundry`
`FOUNDRY_UPNP`	Allow Universal Plug and Play to automatically request port forwarding for the Foundry server port to your local network address.	`false`
`FOUNDRY_UPNP_LEASE_DURATION`	Sets the Universal Plug and Play lease duration, allowing for the possibility of permanent leases for routers which do not support temporary leases. To define an indefinite lease duration set the value to `0`.	`null`
`FOUNDRY_VERSION`	Version of Foundry Virtual Tabletop to install.	`11.315`
`FOUNDRY_WORLD`	The world to startup at system start.	`null`
`TIMEZONE`	Container TZ database name	`UTC`

Node.js variables

Any Node.js variables (NODE_*) supplied to the container will be passed to the underlying Node.js server running FoundryVTT. Listed below are some variables that are particularly useful.

Name	Purpose
`NODE_DEBUG`	`,`-separated list of core modules that should print debug information.
`NODE_EXTRA_CA_CERTS`	When set, the well known "root" CAs (like VeriSign) will be extended with the extra certificates. The file should consist of one or more trusted certificates in PEM format. A message will be emitted (once) with `process.emitWarning()` if the file is missing or malformed, but any errors are otherwise ignored.
`NODE_OPTIONS`	A space-separated list of command-line options that are interpreted before command-line options, so command-line options will override or compound after anything supplied. Node.js will exit with an error if an option that is not allowed in the environment is used, such as `-p` or a script file.
`NODE_TLS_REJECT_UNAUTHORIZED`	If the value equals `0`, certificate validation is disabled for TLS connections. This makes TLS, and HTTPS by extension, insecure. ⚠️ The use of this environment variable is strongly discouraged.

Secrets

Filename	Key	Purpose
`config.json`	`foundry_admin_key`	Overrides `FOUNDRY_ADMIN_KEY` environment variable.
`config.json`	`foundry_license_key`	Overrides `FOUNDRY_LICENSE_KEY` environment variable.
`config.json`	`foundry_password`	Overrides `FOUNDRY_PASSWORD` environment variable.
`config.json`	`foundry_password_salt`	Overrides `FOUNDRY_PASSWORD_SALT` environment variable.
`config.json`	`foundry_username`	Overrides `FOUNDRY_USERNAME` environment variable.

Building from source

Build the image locally using this git repository as the build context:

docker build \
  --build-arg VERSION=11.315.1 \
  --tag felddy/foundryvtt:11.315.1 \
  https://github.com/felddy/foundryvtt-docker.git#develop

Cross-platform builds

To create images that are compatible with other platforms you can use the buildx feature of Docker:

Copy the project to your machine using the Clone button above or the command line:
```
git clone https://github.com/felddy/foundryvtt-docker.git
cd foundryvtt-docker
```

Build the image using buildx:

docker buildx build \
  --platform linux/amd64 \
  --build-arg VERSION=11.315.1 \
  --output type=docker \
  --tag felddy/foundryvtt:11.315.1 .

Pre-installed distribution builds

It is possible to install a Foundry Virtual Tabletop distribution into the Docker image at build-time. This results in a significantly larger Docker image, but removes the need to install a distribution at container startup, resulting in a faster startup. It also moves the user authentication to build-time instead of start-time. Note: Credentials are only used to fetch a distribution, and are not stored in the resulting image.

Build the image with credentials:

docker build \
  --build-arg FOUNDRY_USERNAME='<your_username>' \
  --build-arg FOUNDRY_PASSWORD='<your_password>' \
  --build-arg VERSION=11.315.1 \
  --tag felddy/foundryvtt:11.315.1 \
  https://github.com/felddy/foundryvtt-docker.git#develop

Or build the image using a temporary URL:

docker build \
  --build-arg FOUNDRY_RELEASE_URL='<temporary_url>' \
  --build-arg VERSION=11.315.1 \
  --tag felddy/foundryvtt:11.315.1 \
  https://github.com/felddy/foundryvtt-docker.git#develop
