In this first part, we will talk about multi-stage builds, because that's where anyone should start if they want to reduce the size of their images. We will also explain the differences between static and dynamic linking, as well as why we should care about that. This will be the occasion to introduce Alpine. ## 1º Changelog Meetup DevFeed: [1º Changelog Meetup]() Original publisher: [Read original article]() Author: Carlos Alexandro Becker Published: 2017-11-21T00:00:00Z Content type: article Language: en Sources: [Carlos Becker]() Topics: [Go Language](), [Docker](), [docker images](), [Homebrew](), [Linux]() Tags: [build](), [docker](), [docker-images](), [go](), [homebrew](), [linux](), [meetup](), [packages](), [release]() ### AI overview A presentation covered building and releasing Go binaries, including cross-compilation, Docker images, Linux packages, and Homebrew, with GoReleaser featured at the end. ### Source excerpt I showed how to build and release binaries in Go, including cross-compiling, Docker images, Linux packages and Homebrew, featuring GoReleaser on the end. ## Some useful commands in Docker DevFeed: [Some useful commands in Docker]() Original publisher: [Read original article]() Author: Tom Published: 2016-02-11T00:00:00Z Content type: tutorial Language: en Sources: [Tomasz Gągor]() Topics: [Docker](), [Containers](), [docker images]() Tags: [build](), [commands](), [container](), [containers](), [docker](), [docker-images](), [image](), [logs](), [running](), [volumes]() ### AI overview A practical Docker tutorial listing commands for managing containers, images, and volumes, running and entering containers, viewing build logs, and building an image from the current directory. ### Source excerpt I started playing with Docker and here I will write some commands that where not so obvious at beginning 😃 List running containers: docker ps List also not running containers: docker ps -a Remove all containers (be careful with that): docker rm $(docker ps -a -q) Remove all images: docker rmi $(docker images -q) Docker won't remove any old volumes used by containers, so after some time you may be interested in deleting them all: ## Docker Commands and Tips for Managing Containers and Images DevFeed: [Docker Commands and Tips for Managing Containers and Images]() Original publisher: [Read original article]() Author: Carlos Alexandro Becker Published: 2015-05-10T00:00:00Z Content type: tutorial Language: en Sources: [Carlos Becker]() Topics: [Docker](), [container](), [docker images]() Tags: [commands](), [container](), [containers](), [disk-space](), [docker](), [docker-images](), [mac]() ### AI overview A collection of Docker commands and practical tips for managing containers and images, including stopping containers, removing stopped containers, deleting images, and using Kitematic on Mac. ### Source excerpt Like my old post on git, this is somewhat a collection of useful Docker commands/tricks/whatever.
