A small utility to update tg-spam samples from remote git repository

The utility is designed to be run either as a docker container or as a standalone script or as a part of a cron job. It detects the environment and acts accordingly. For example, if it is run as a docker container, it will update the samples every minute. However, if it runs as a part of a cron job, it will update the samples once per run, only if the remote repository has changed since the last update (or if the local repository is missing).

The docker image is available at docker hub and from github packages. The following command arguments are supported:

• first argument is a git repository url (required)
• second argument is a path to the local repository (optional, default is ./samples)

Example of running the utility as a docker container:

docker run -d --name tg-spam-updater -v $(pwd)/tg-spam-samples:/samples ghcr.io/umputun/tg-spam.updater https://github.com/radio-t/tg-spam-samples.git /samples

The command above will run the updater as a docker container and mount the local directory ./tg-spam-samples to the container's /samples directory. The updater will clone the remote repository to the local directory and then update it every minute.

Example of running the utility from the docker-compose:

services:
  tg-spam-updater:
    image: ghcr.io/umputun/tg-spam-updater:latest
    restart: always
    user: "1000:1000" # run with the same user as the host machine to avoid permission issues
    command: ["https://github.com/radio-t/tg-spam-samples.git", "/samples"]
    volumes:
      - ./tg-spam-samples:/samples

permission issues

If the updater is run as a Docker container, there may be a discrepancy in file ownership between the host and the container. By default, containers run with a user ID (UID) of 1001. If the host's directory is owned by a different user, this can lead to permission issues. To circumvent this, you can use the APP_UID environment variable, either from the command line or within a Docker Compose file. For instance: docker run -d --name tg-spam-updater -e APP_UID=502 ..... It's also recommended to create the samples directory on the host before running the container.
