Different ways to compile and deploy golang using docker to produce faster/smaller images

compile the binary using current arch

go build -o sample-binary sample.go

execute it in your arch watch it work

./sample-binary

compile the binary using cross arch (from osx to linux)

GOOS=linux go build -o sample-binary sample.go

execute it in your arch and watch it fail

./sample-binary

execute previous linux binary in an ephemeral alpine container and watch it work

docker run -v $(PWD):/root -it --rm alpine:latest /root/sample-binary

we docker now

build the Dockerfile using Dockerfile-single, produces a golang:alpine image with all os deps

docker build . -t golang-deploy-examples-single:latest -f Dockerfile-single

build the Dockerfile using Dockerfile-single, produces a golang:alpine image with all os deps, stripping debug and using upx

docker build . -t golang-deploy-examples-single-optimized:latest -f Dockerfile-single-optimized

build the Dockerfile using Dockerfile-stages, produces an alpine and copies binary from previous docker step

docker build . -t golang-deploy-examples-stages:latest -f Dockerfile-stages

build the Dockerfile using Dockerfile-stages-optimized, produces an alpine and copies binary from previous docker step, stripping debug and using upx

docker build . -t golang-deploy-examples-stages-optimized:latest -f Dockerfile-stages-optimized

build using FROM SCRATCH and optimize debug tables, compress upx

docker build . -t golang-deploy-examples-scratch:latest -f Dockerfile-scratch

execute with autorestart flag

docker run -dt --restart always -m 64M --name golang-deploy-examples-scratch golang-deploy-examples-scratch:latest

log it

docker logs golang-deploy-examples-scratch --follow

check the container status

docker stats

cleanup

stop running containers

docker stop golang-deploy-examples-scratch

remove containers

docker rm golang-deploy-examples-scratch

remove images
