Quick Start Template for Golang (with Go Modules for 1.15)
This repository contains a semver utility from fmahnke/shell-semver.
I've designed the repository to be working as a containerised application. The container utilises multi-stage builds to optimise the size and dependency resolutions for the application.
Alpine Linux is a Linux distribution based on
muslandBusyBox, designed for security, simplicity, and resource efficiency.
Alpine Linux is a very small and completed linux container where it should satisfies all the basic requirements.
The finalised product would be running on alpine:3. Any additional packages can be directly downloaded from the alpine repositories via apk command.
However, to compensate the size, alpine has opt to use musl gcc compiler. For perfomance optimisation it would recommended for go developers to compile the static library into your application as the system's C libraries will not inference with the application (CGO_ENABLED).
There's pros and cons of using musl lib, but if you're not keen of using musl, you can choose glibc on distroless option.
"Distroless" images contain only your application and its runtime dependencies.
Distroless is the recommended way to run a container in production by Google. Restricting what's in your runtime container to the only necessary items are yield fast and secure container. It reduces a potential CVE that you might face with the underlying dependencies.
Be warned that distroless images lacks of shell access thus, meaning that it is impossible to enter the container to troubleshooting the applications.
