Juncoding Agent Skills
A DevOps skill for running many apps on one EC2 box
About
A single-purpose infrastructure skill by Bill Zhou: ec2-docker-host teaches an agent to run many independent apps side-by-side on one AWS EC2 box, with a shared Caddy reverse proxy and auto-TLS, shared Postgres/Mongo/Redis, and per-app containers, ports, databases, and secret namespaces. It includes idempotent, neighbor-safe ops scripts and a discovery-before-change doctrine so the agent never stomps on a neighbor's workload. The strength is how concrete it is — actual scripts with a safety doctrine, not abstract advice. The limitation: exactly one skill, 0 stars, 2 commits — and the scripts run sudo against real servers, so read them before the first run.
What it can do
- Provision a fresh EC2 host (instance, Elastic IP, security group, Docker, shared DB and proxy stack)
- Adopt and discover an existing host safely
- Deploy monorepo or polyrepo apps as isolated units
- Backups: logical DB dumps, volume snapshots, off-host sync
- Shared Caddy reverse proxy with auto-TLS
- Idempotent, neighbor-safe ops scripts with validation
