April 30, 2017 - A common workaround for building Golang application in Docker is to have 2 Dockerfiles - one to perform a build and another to ship the results of the first build without tooling in the first image. It called Builder Pattern.

March 26, 2022 - I finally wrote the following Dockerfile, no one line more, no one line less. FROM golang:alpine AS builderWORKDIR /buildADD go.mod . COPY . . RUN go build -o hello hello.go FROM alpineWORKDIR /build COPY --from=builder /build/hello /build/helloCMD [".

# File: Dockerfile # Supports multi-stage build FROM golang as builder WORKDIR /app COPY * /app/ RUN env GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -o server . FROM alpine:latest WORKDIR /root/ COPY --from=builder /app/server .

Easypanel, unlike many other panels, can run any application. It creates Docker images for Node.js, Ruby, Python, PHP, Go, and Java apps using Heroku Buildpacks. You can bring your own Dockerfile if you require greater control.

Testcontainers for Go gives you the ability to build an image and run a container from a Dockerfile.

July 18, 2022 - It was actually very common to have one Dockerfile to use for development (which contained everything needed to build your application), and a slimmed-down one to use for production, which only contained your application and exactly what was needed to run it. This has been referred to as the “builder pattern”. Maintaining two Dockerfiles is not ideal. first we will make an golang image from docker hub official Golang image and give an alias name builder .

December 18, 2023 - For a quick test setup, you could get away with writing a basic Dockerfile, like so: ARG GO_VERSION=1.21.3 FROM golang:${GO_VERSION} WORKDIR /src COPY . . RUN go mod download -x RUN CGO_ENABLED=0 go build -o /bin/server.

Dockerfiles to build Docker images for your Go app. It makes use of Docker's multi-stage build feature to create the Go application binary, and then attach it to a minimal base image.

June 5, 2018 - I have built a Go project, which is a web application. It has packages and imports from different github repositories (such as Gorilla mux). However, there aren’t really any docs on how to use Docker with a Go project t…

# syntax=docker/dockerfile:1 # A sample microservice in Go packaged into a container image. FROM golang:1.19 # ...

In your Dockerfile, writing something along the lines of the following will compile and run your project (assuming it uses go.mod for dependency management): FROM golang:1.25 WORKDIR /usr/src/app # pre-copy/cache go.mod for pre-downloading dependencies and only redownloading them in subsequent builds if they change COPY go.mod go.sum ./ RUN go mod download COPY .

# syntax=docker/dockerfile:1 FROM golang:1.25 AS build WORKDIR /src COPY go.mod go.sum ./ COPY vendor* ./vendor/ RUN --mount=type=cache,target=/go/pkg/mod \ --mount=type=cache,target=/root/.cache/go-build \ if [ -d "vendor" ]; then \ echo "Using vendored dependencies" && \ go mod verify; \ else \ echo "Downloading dependencies" && \ go mod download && go mod verify; \ fi COPY .

September 26, 2014 - EXPOSE 8080 · This Dockerfile specifies how to construct a container that runs outyet, starting with the basic dependencies (a Debian system with Go installed; the official golang docker image), adding the outyet package source, building it, and then finally running it.

November 3, 2021 - If your repository does not have a .devcontainer/devcontainer.json file in it, you'll be asked to pick a starting point from a filterable list or an existing Dockerfile or Docker Compose file (if one exists).

October 18, 2023 - We are creating this Dockerfile inside /go-docker directory: ... # Use the official Golang image as a base FROM golang:latest # Set the working directory in the container WORKDIR /go-docker # Copy the local package files to the container’s workspace. COPY .

September 5, 2024 - Thanks a lot everyone, have updated the Dockerfile to use latest Golang, and made it more production ready and secure.

Multi-stage Dockerfile (with Go modules and unit tests) Let’s see these workflows in order. The most simple pipeline that you can create is just two steps: ... version: '1.0' steps: main_clone: title: Cloning main repository... type: git-clone repo: 'codefresh-contrib/golang-sample-app' revision: master git: github MyAppDockerImage: title: Building Docker Image type: build image_name: my-golang-image working_directory: ./ tag: full dockerfile: Dockerfile
