Manual deployment by copying project files, install docker-compose and running itДЄ common usage of Compose is to copy the project source with the docker-compose.yml, install docker-compose on the target machine where we want to deploy the compose app and finally run it. There are three ways to deploy it on the remote host: 1.

Assume we have SSH access to a remote docker host with a key-based authentication to avoid a password prompt when deploying the application. The sample application can be deployed on a remote host in several ways. Hello from Docker! Running on a remote hostДЄ remote Docker host is a machine, inside or outside our local network which is running a Docker Engine and has ports exposed for querying the Engine API. Query the web service on port 8080 to get the hello message from the go backend. doneД¬heck all containers are running and port 80 of the frontend service container is mapped to port 8080 of the localhost as described in the docker-compose.yml.Д¬ONTAINER ID IMAGE COMMAND CREATED STATUSД 7b55d101e74 nginx:latest 'nginx -g 'daemon of.' 6 seconds ago Up 5 secondsД .0.0.0:8080->80/tcp hello-docker_frontend_1Д¤8cdf1b8417c hello-docker_backend '/usr/local/bin/back.' 6 seconds ago Up 5 seconds hello-docker_backend_1 To deploy the application we defined previously, go to the project directory and run docker-compose:Д¬reating network 'hello-docker_default' with the default driverД¬reating hello-docker_frontend_1. The project structure and the Compose file can be found below: The frontend service will run an nginx proxy that will forward the HTTP requests to a simple Go app server.ДЄ sample with all necessary files for this exercise can be downloaded from here or any other sample from the Compose samples repository can be used instead. LetвЂ™s define a Compose file describing an application consisting of two services: frontend and backend. This is available starting with release 1.26.0-rc2 of docker-compose. Make sure you get docker-compose with the context support feature.

For Linux you will need to get Docker Engine and docker-compose.

Docker Engine and Compose are included in Docker Desktop for Windows and macOS. Finally, we will exercise the use of Docker Contexts with docker-compose to deploy on remote engines.Д«efore proceeding, docker and docker-compose must be installed on the localhost. Further weвЂ™ll have a look at a Docker Context and the information it holds to allow us to safely connect to remote Docker engines.

WeвЂ™ll start defining a sample application to use throughout this exercise, then weвЂ™ll show how to deploy it on the localhost. The goal of this post is to show how to use contexts to target different environments for deployment and easily switch between them. To address this issue, we rely on Docker Contexts to securely deploy Compose applications across different environments and manage them effortlessly from our localhost. This is not very user friendly and managing deployments of Compose applications across multiple environments becomes a burden. In such cases, the challenge is that docker-compose provided support for running on remote docker engines through the use of the DOCKER_HOST environment variable and -H, вЂ“host command line option. From here, we can get the application running locally in a few seconds with a single `docker-compose up` command.ДЄs developers look to have the same ease-of-deployment in CI pipelines/production environments as in their development environment, we find today docker-compose being used in different ways and beyond its initial scope. All we need to do is write a Compose file containing the configuration for the applicationвЂ™s services and have a running Docker engine for deployment. The docker-compose tool is pretty popular for running dockerized applications in a local development environment.
