Examples of running a nodejs app under Docker with various process managers.
- Plain Docker
- supervisor
- s6
- nodemon
- forever
Examples have both the Debian based node image and
the Alpine mhart/alpine-node image using Node v8.9.3
The node app will run as nobody in each setup.
The app must handle the sigint (ctrl-c) and sigterm (docker stop) signals when running as PID 1 in Docker
docker build -f Dockerfile.plain -t dply/node-docker-demo-app:plain .
docker run -dp 8080:8080 --restart always dply/node-docker-demo-app:plain
curl http://localhost:8080
Uses the s6-overlay project.
docker build -f Dockerfile.s6 -t dply/node-docker-demo-app:s6 .
docker run -dp 8080:8080 dply/node-docker-demo-app:s6
curl http://localhost:8080
Forever doesn't handle sigint and sigterm when running a script in the foreground.
docker build -f Dockerfile.plain -t dply/node-docker-demo-app:forever .
docker run -dp 8080:8080 dply/node-docker-demo-app:forever
curl http://localhost:8080
-ti is required to attach and control nodemon
docker build -f Dockerfile.nodemon -t dply/node-docker-demo-app:nodemon .
docker run -dtip 8080:8080 dply/node-docker-demo-app:nodemon
curl http://localhost:8080
Supervisor is easy to configure and provides an XMLRPC API to programatically manage your services running in Docker
docker build -f Dockerfile.plain -t dply/node-docker-demo-app:supervisor .
docker run -dp 8080:8080 dply/node-docker-demo-app:supervisor
curl http://localhost:8080
The ./make.sh script can build and run everything
The default is ./make.sh build
./make.sh build_s6
./make.sh run s6
./make.sh run s6-alpine
./make.sh test
./make.sh build plain
./make.sh run plain
etc
