If you’re using a Mac and want to use MySQL without making many installation changes, you’ve come to the right place. All these problems can be alleviated by installing a MySQL container inside Docker. You will also have to make changes to your bash profile to access mysql in terminal.

If you were to install using the official installer, you’d have to give administrator rights. Homebrew is also a good example to install command line applications at a user level. Programs like VSCode and Atom are good examples of that when all you do is drag the application icon to the Applications folder. Note the “Processed by container ID “ at the bottom of the page.I’ve never liked to make changes to my laptop by providing my admin credentials to install various tools, like MySQL because I love doing things at a user level.

Swarm will also do basic load balancing.

In a multi-node environment, Swarm will spread out the replicas however you want.

So when the result app calls on the database, it connects to and the Swarm takes care of directory the service to `db`.

The services all refer to each other by name.

There’s a lot going on here but here are some points to highlight:

The code for all these components is in our Example Voting App repo on GitHub. Open up different browsers to add in additional votes if you want. On localhost:5001 you can see the results of the vote. You can vote for cats or dogs, whichever you like better.

A results page running in Node.js that draws from the database.

A worker that goes into the redis instance, pulls out data and pushes it into the database.

A redis instance to store key value pairs.

A voting page in Flask that pushing results to redis.

So what happened? With the simple compose file format you created an application that has 5 components: You can run this a few times until all the replicas say 1/1.

All with a name vote_ plus something like vote_db. This will show you the 5 services, all with 1 replica. Then, copy the contents of this file into a file called docker-stack-simple.yml.įrom the command line in the same directory as that file, type the following commands. Make sure Swarm is selected and hit Apply if needed. Open Docker Desktop and select Preferences-> Kubernetes. Give it a try with a few simple steps.įirst, make sure you are using Swarm as your orchestrator. Swarm uses the Docker command line or the Docker Compose file format with a few additions. Managers run the swarm cluster, making sure nodes can communicate with each other, allocate applications to different nodes, and handle a variety of other tasks in the cluster. Swarm mode uses managers and workers to run your applications. After joining a swarm, they are referred to as nodes. The machines in a swarm can be physical or virtual. After that has happened, you continue to run the Docker commands you’re used to, but now they are executed on a cluster by a swarm manager. Docker Desktop is the easiest way to get started with either Swarm or Kubernetes.Ī swarm is a group of machines that are running Docker and joined into a cluster. If you've read anything about Docker, you have probably heard of Kubernetes and Docker swarm mode. While it is easy to run an application in isolation on a single machine, orchestration allows you to coordinate multiple machines to manage an application, with features like replication, encryption, load balancing, service discovery and more. To run it, open a command line and navigate to the same directory as the docker-compose.yml file. It also specifies the password, which you wouldn’t want to do in a real world situation. There’s a lot of details in there but basically you can see that it specifies the images to be used, the service names, the ports available, and networks the different services are on. To try it out, open a text editor and paste the text from this file.

Docker Compose handles service discovery directly, allowing the app to reference the service directly and Docker will route traffic to the right container. We’ve pushed two images to the Docker Hub under the dockersamples repo. You can check out the app in our dockersamples GitHub repo. This sample uses a simple Java web app running in Tomcat with a MySQL database. Docker Compose installs automatically with Docker Desktop.Ī multi-container app is an app that has multiple containers running and communicating with each other. Then, with a single command, you create and start all the services from your configuration. With Compose, you use a YAML file to configure your application’s services. Easily connect multiple services togetherĭocker Compose is a tool for defining and running multi-container Docker applications.
