Dockture is a program written in Rust that watches Docker containers for problems. Docker containers are small, self-contained packages that run applications. When a container crashes, uses too much memory or CPU, or logs error messages, Dockture notices and sends alerts through email, Discord, or Slack so you can respond quickly. Setting it up is straightforward. You can install a pre-built version with a single shell command, or build it from the source code using Rust's standard build tool. Once installed, you create a configuration file in TOML format (a simple text-based format) where you specify your alert destinations, such as your email server details or Discord and Slack webhook URLs. If you prefer not to edit the file by hand, running the setup wizard walks you through the options interactively. The configuration lets you fine-tune what Dockture watches for. You can enable automatic restarts of crashed containers, turn on anomaly detection that flags unusual resource usage, and define custom keywords like "error" or "panic" that trigger alerts when they appear in container logs. You can also control which alert types go to which channel, so crashes might go to both email and Discord while less urgent warnings only go to Discord. Dockture offers several commands for everyday use. You can check container metrics and disk usage, stream colorized logs from a specific container, test your email or webhook settings before relying on them, and view or update your configuration. It also supports running as a background service through systemd, which means it starts automatically and keeps running even after reboots. For teams already using Docker Compose, there is a ready-made configuration to run Dockture alongside other containers. The project is licensed under MIT and has a small number of GitHub stars. Full documentation lives in the wiki directory inside the repository.
