In this lab you will run a popular, free, lightweight container and explore the basics of how containers work, how the Docker Engine executes and isolates containers from each other. If you already have experience running containers and basic Docker commands you can probably skip this intro exercise.MULTI-STAGE BUILDS
Multi-staged builds. A common pipe-line for building applications in Docker involves adding SDKs and runtimes, followed by adding code and building it. The most efficient way to get a small image tends to be to use 2-3 Dockerfiles with different filenames where each one takes the output of the last. This is referred to as the Builder pattern in DOCKER CLI FORMATTING Docker has organized commands into a docker syntax with the above nouns. There are also aliases to many commands at the top level. For example, docker run is the same as docker container run.To see the verbs available to docker container, we can run:. docker container--help

Config files can be mounted inside services’ containers, avoiding the need to bake configuration into images. Configuration files are similar to secrets, and in fact the CLI and API show few differences between the two. DOCKER COMPOSE WITH SWARM SECRETS Automatic provision. In this example we’ll let compose automatically create our secrets and provision them through compose with the defined secret file. Create a new secret and store it in a file: echo "shh, this is a secret" > mysecret.txt. Use your secret file in your composestack as follows:

DOCKER IMAGES DEEPER DIVE Image creation from a container. Let’s start by running an interactive shell in a ubuntu container. docker container run -ti ubuntu bash. As we’ve done in the previous lab, we will install the figlet package in this container. apt-get update apt-get install -y figlet. We then exit from this container. exit. SWARM MODE INTRODUCTION FOR IT PROS Swarm Mode tells Docker that you will be running many Docker engines and you want to coordinate operations across all of them. Swarm mode combines the ability to not only define the application architecture, like Compose, but to define and maintain high availability levels, scaling, load balancing, and more. BUILDING AND DISTRIBUTING APPS WITH DOCKER, JENKINS AND Browse to Jenkins and click log in at the top right of the screen. Log in with username pi and password pi (you may have to wait a few moments for Jenkins to start up). 2. Add your Docker Hub token. Your Jenkins server is configured to build a simple app, run some tests and push the image to Docker Hub. DOCKER NETWORKING HANDS-ON LAB Step 3: Inspect a network. The docker network inspect command is used to view network configuration details. These details include; name, ID, driver, IPAM driver, subnet info, connected containers, and more. Use docker network inspect to view configuration details of the container networks on your Docker host. LIVE DEBUGGING NODE.JS WITH DOCKER Start debugging. Open up the app directory in VSCode. Head over to the debugger by clicking the bug icon in the left-hand sidebar. Create a boilerplate debugger config by clicking the gear icon and selecting “Node.js” in the dropdown.

This is a short collection of tips and tricks showing how Docker can be useful when working with Go code. For instance, I’ll show you how to compile Go code with different versions of the Go toolchain, how to cross-compile to a different platform (and test the result!), or how to produce really small container images.

Launch the pod. The first container in the pod is created by launching a container mypod with a long-running process. Usually this is an infinite loop but in our case, the primary container will run for one hour (3600 seconds): docker container run -d --name mypod alpine sleep3600.
SECURITY LAB: CAPABILITIES Lab: Capabilities. Difficulty: Advanced. Time: Approximately 30 minutes. In this lab you’ll learn the basics of capabilities in the Linux kernel.

FIRST ALPINE LINUX CONTAINERS First Alpine Linux Containers. In this lab you will run a popular, free, lightweight container and explore the basics of how containers work, how the Docker Engine executes and isolates containers from each other.

DOCKER IMAGES DEEPER DIVE Image creation from a container. Let’s start by running an interactive shell in a ubuntu container. docker container run -ti ubuntu bash.

This is a short collection of tips and tricks showing how Docker can be useful when working with Go code. For instance, I’ll show you how to compile Go code with different versions of the Go toolchain, how to cross-compile to a different platform (and test the result!), or how to produce really small container images. IN-CONTAINER JAVA DEVELOPMENT: INTELLIJ Set a breakpoint in UserServiceImpl on the findByLogin method. Log in again and look at the values for the breakpoint. The ‘passwd’ variable is z0ol which matches the password for the user moby..

From the previous command, get the ID of the newly created image and tag it so it’s named ourfiglet: docker image tag ourfiglet docker image ls. Now we have the more friendly name “ourfiglet” that we can use toidentify our image.

A simple, interactive and fun playground to learn DockerLogin
docker
Start
Play with Docker (PWD) is a project hacked by Marcos Liljedhal and Jonathan Leibiusky and sponsored by Docker Inc. PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode. Under the hood
Docker-in-Docker (DinD) is used to give the effect of multiple VMs/PCs. In addition to the playground, PWD also includes a training site composed of a large set of Docker labs and quizzes from beginner to advanced level available at training.play-with-docker.com.
