Alternatively, you can right-click on your Compose file and select the Compose Up option for the VS Code side bar. Add the -d flag to run everything in the background. Start up the application stack using the docker-compose up command. Now that you have the docker-compose.yml file, you can start it up!įirst, make sure no other copies of the app and database are running ( docker ps and docker rm -f ). version: "3.7"Īt this point, the complete docker-compose.yml should look like this: version: "3.7" version: "3.7"įinally, you only need to specify the environment variables. There are many more options available though. By simply providing only the volume name, the default options are used. You need to define the volume in the top-level volumes: section and then specify the mountpoint in the service config. However, that doesn't happen when running with Compose. When you ran the container with docker run, the named volume was created automatically. network todo-app -network-alias mysql \įirst, define the new service and name it mysql so it automatically gets the network alias.
#Yarn run dev default port windows#
The command that you used for that container was the following (replace the \ characters with ` in Windows PowerShell): docker run -d \
Now, it's time to define the MySQL service. version: "3.7"įinally, migrate the environment variable definitions using the environment key. One advantage of Docker Compose volume definitions is you can use relative paths from the current directory. Volumes also has a short and long syntax. Next, migrate both the working directory ( -w /app) and the volume mapping ( -v $:/app) by using the working_dir and volumes definitions. You'll use the short syntax here, but there is also a more verbose long syntax available as well. Migrate the -p 3000:3000 part of the command by defining the ports for the service.
#Yarn run dev default port install#
version: "3.7"Ĭommand: sh -c "yarn install & yarn run dev" So, go ahead and move that into the file. Typically, you'll see the command close to the image definition, although there is no requirement on ordering. The name will automatically become a network alias, which will be useful when defining the MySQL service. docker run -dp 3000:3000 \įirst, define the service entry and the image for the container. To remember, this was the command you used to define your app container (replace the \ characters with ` in Windows PowerShell). version: "3.7"Īnd now, you'll start migrating a service at a time into the compose file. Next, define the list of services (or containers) you want to run as part of your application. You can look at the Compose file reference for the current schema versions and the compatibility matrix. In most cases, it's best to use the latest supported version. In the compose file, we'll start off by defining the schema version. docker-compose versionĪt the root of the app project, create a file named docker-compose.yml. If you are on a Linux machine, you will need to install Docker Compose using the instructions here.Īfter installation, you should be able to run the following and see version information. If you installed Docker Desktop for either Windows or Mac, you already have Docker Compose! Play-with-Docker instances already have Docker Compose installed as well. So, how do you get started? Install Docker Compose
In fact, you might see quite a few projects on GitHub/GitLab doing exactly this now. Someone would only need to clone your repo and start the compose app. The big advantage of using Compose is you can define your application stack in a file, keep it at the root of your project repo (it's now version controlled), and easily enable someone else to contribute to your project. With Compose, you can create a YAML file to define the services and with a single command, can spin everything up or tear it all down. Docker Compose is a tool that was developed to help define and share multi-container applications.
