Overcast

Project483

Provision DigitalOcean servers and run commands or scripts across SSH-managed clusters.

What you can build

  • Build a local reporting script that reads Overcast instance and cluster attributes and produces a CSV of server names, IP addresses, SSH ports, and selected DigitalOcean image details.
  • Build a release wrapper that takes a release script and ordered cluster list, invokes Overcast to run the script on one cluster at a time, and saves each stage's output.
  • Build a drift checker that pulls a chosen configuration file from each named instance into separate local copies, hashes them, and outputs groups of matching and differing files.
  • Build a checker that collects Overcast's machine-readable exposed-port output for Ubuntu hosts, compares it with a supplied per-cluster allowlist, and reports unexpected ports.
  • Build a collector that runs uptime, memory, and disk commands across a target cluster, pulls specified log files per instance, and packages the outputs with host labels.

Try this prompt

Build a small local release runner around Overcast. Accept a release script and an ordered list of cluster names, run the script on each cluster sequentially through Overcast, and save timestamped output per stage without deleting or overwriting earlier logs. Stop on the first failed stage and report which cluster failed. Use only documented Overcast commands and options; include setup instructions and a sample input and output.

Get started

  1. Install prerequisites

    Install Node.js on macOS or Linux, then install Overcast through npm as documented. Windows use is possible but unsupported.

  2. Configure access

    Initialize an Overcast configuration and provide a DigitalOcean API token for provider commands. Configure SSH keys or use the OpenSSH key selection already available on your system.

  3. Define targets

    Use the documented clusters and instance configuration to organize servers. Overcast can also add existing instances; its README contains the command reference for running scripts and transferring files.

License & notes

MITThe repository is MIT-licensed; retain its copyright and license notice when distributing copies. Overcast itself has no listed price. Running it requires Node.js and SSH access; DigitalOcean droplets and any other infrastructure you use may incur provider charges. No dollar amounts or plan terms are supplied.

  • Overcast is not declarative configuration management and does not track desired server state; it also is not a process manager or monitoring system.
  • Provisioning is documented for DigitalOcean. Remote operations depend on SSH access, and the documented firewall commands expect Ubuntu and are untested on other distributions.
  • Commands and scripts execute on remote servers; review targets and destructive actions carefully. Windows use is unsupported.
