Developer Tools
Concord, an open source workflow and process automation server that runs YAML flows through a REST API and a web console, with the server, an execution agent and its database ready on first boot.
Overview
Concord is an open source workflow orchestration server that automates operational processes as version controlled flows. A flow is a YAML process the server accepts through a REST API or its web console, queues, and hands to a pluggable agent that executes each step, so teams can codify provisioning, deployment, approvals and scheduled jobs as repeatable automation rather than ad hoc scripts. The web console gives an authenticated view of processes, projects, organisations and their live logs, while the REST API lets pipelines and external systems start flows, pass parameters and read results. Concord keeps its state, secrets store and audit history in a database, giving a durable record of every automated run.
Why the cloudimg image
cloudimg ships Concord hardened and fully patched, with the server, an execution agent and a local database wired together behind an nginx TLS reverse proxy so the console and REST API respond on first boot. It is secure by default with no shared credential in the image: the database ships empty and first boot mints a unique administrator API token, generates a per instance TLS certificate and rotates the internal service secrets before anything is exposed, so no default login exists. All automation state lives on a dedicated data volume, and every image comes with a deploy guide tested against the exact build and 24/7 cloudimg support.
Common uses
- Orchestrating provisioning, deployment and operational runbooks as code
- A self service automation console for teams to run and track flows
- Driving scheduled and event triggered jobs through a REST API
