Minimalist TypeScript/Node Docker Example
This repo provides an example of building minimalist docker build for TypeScript/NodeJS based microservice.
So the most interesting part is to observe:
Dockerfile represents 3-stage building process. First phase is to run
ts/node build under a target platform, which is based on Alpine Linux. Second
phase compress generated binary executable using gzexe. Third, and the last
phase creates a release image containing only minimalist Alpine image, pre-built
compressed binary of microservice and working gzip/gzexe commands.
package.json provides a basic command set to automate local and docker builds
of microservice.
With current docker build implementation it results into 27.1 MB image
size production, which includes 18.4 MB pre-built compressed ts/node
microservice binary inside, which results into 21.6 MB compressed docker image
size for pulling.
Is it possible to have less?
Author would be greatly appreciated for any suggestions and contributions of further optimizations and improvements to this example.
