Docker usage instructions

Docker distribution of DiscordChatExporter provides a way to run the app in a virtualized and isolated environment. Due to the nature of Docker, you also don't need to install any prerequisites otherwise required by DCE.

Note that only the CLI flavor of DiscordChatExporter is available for use with Docker.

Pulling

This will download the Docker image from the registry to your computer. You can run this command again to update when a new version is released.

docker pull tyrrrz/discordchatexporter:stable

Note the :stable tag. DiscordChatExporter images are tagged according to the following patterns:

• stable: Latest stable version release and maps to the latest GitHub release. This tag is updated with release of each new version. Recommended for personal use.
• latest: Built from the latest commit and maps to the latest CI build on GitHub. This tag is updated with each new commit to master branch. Not recommended for everyday use, but you can use it if you want to try out some features that haven't been officially released yet.
• x.y.z (e.g. 2.30.1): Fixed version release and maps to the corresponding tag on GitHub. This tag is never updated once that version has been released. Recommended for use in automation scenarios.

You can see all available tags here.

Usage

To run the CLI in Docker and render help text:

docker run --rm tyrrrz/discordchatexporter:stable

To export a channel:

docker run --rm -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID

If you want colored output and real-time progress reporting, pass the -it (interactive) option:

docker run --rm -it -v /path/on/machine:/out tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID

Note the -v /path/on/machine:/out option, which instructs Docker to bind the /out directory inside the container to a path on your host machine. Replace /path/on/machine with the directory you want the files to be saved at.

Note

: If you are running SELinux, you will need to add the :z option after /out, e.g.:

docker run --rm -v /path/on/machine:/out:z tyrrrz/discordchatexporter:stable export -t TOKEN -c CHANNELID

For more information, refer to the Docker docs SELinux labels for bind mounts page.

You can also use the current working directory as the output directory by specifying:

• -v $PWD:/out in Bash
• -v $pwd.Path:/out in PowerShell

For more information, please refer to the Dockerfile and Docker documentation.

To get your Token and Channel IDs, please refer to this page.

Environment variables

DiscordChatExpoter CLI accepts the DISCORD_TOKEN environment variable as a fallback for the --token option. You can set this variable either with the --env Docker option or with a combination of the --env-file Docker option and a .env file.

Please refer to the Docker documentation for more information.

Permission issues with Linux hosts

When bounding volumes between the container and the host, files mirrored from the Docker container will be owned by the Docker user (in most setups this is root). Please refer to this issue comment for instructions on how to override this behavior.
