docker-images-golang

Images for docker containers:

• Lint environment container is for lint golang app source code. Uses golangci-lint to lint code with custom config.
• Test environment container is for testing golang app. Has all things to test golang sources with go test.
• Build environment container is for building golang app. Has all things to build golang app with go modules.
• Base environment container is for running golang app. Has all things to run binaries in formalized application structure. Exposes 8080 port and run service command: /app/bin/service. Only thing you must do is copy binaries, Makefile (if needed), migrations (if needed) and application default configuration.

Building image

Simply run a make command

make build-base-image   # to build base image
make build-build-image  # to build building image
make build-linter-image # to build linterr image
make build-test-image   # to build test image
make build-all          # to build all images

Pushing image

Simply run a make command

make push-base-image   # to push base image
make push-build-image  # to push building image
make push-linter-image # to push linterr image
make push-test-image   # to push test image
make push-all          # to push all images

Images usage

Common usage application Dockerfile:

FROM spacetabio/docker-lint-golang:1.12-latest as lint-env

COPY . /app
RUN make lint

# ----

FROM spacetabio/docker-test-golang:1.12-latest as test-env

COPY . /app
RUN make test

# ----

FROM spacetabio/docker-build-golang:1.12-latest as build-env

COPY . /app
RUN make all

# ----

FROM spacetabio/docker-base-golang:1.12-latest

COPY --from=build-env /app/bin/*                  /app/bin/
COPY --from=build-env /app/Makefile               /app/
COPY --from=build-env /app/migrations/*           /app/migrations/
COPY --from=build-env /app/configuration/defaults /app/configuration/defaults

If private packages are used, build it with Dockerfile below and command: docker build -t <imagename>:<tag> --build-arg TOKEN="$(cat ~/.ci-token)" --build-arg PRIVATE_REPO="private.repo.url" .

FROM spacetabio/docker-test-golang:1.12-latest as test-env

ARG TOKEN
ARG PRIVATE_REPO
RUN git config --global url."https://ci-token:${TOKEN}@${PRIVATE_REPO}/".insteadOf 'https://${PRIVATE_REPO}/'

COPY . /app
RUN make test
