NET.Compose Is used to define and run multiple containers Docker Application tools. This quick-start guide demonstrates how to use Docker Engine on Linux and Docker Compose to set up and run the sample ASP.NET Core application using the. Developers building both docker-compose and Swarm-based apps, and apps destined for deployment on Kubernetes can now get a simple-to-use development. Docker for Mac and Windows are the most popular way to configure a Docker dev environment and are used everyday by hundreds of thousands of developers to build, test and debug containerized apps.Stop by daily for new game releases and new game downloads for your Mac. By using Docker, wher.If you don't already know YML File configuration , You can read it first. For ROS 1, it requires Ubuntu Linux and for ROS 2, while it allows Mac, Windows and others, the underlying libraries are still not available on all architectures and setup is complex. It is challenging to set it up. Recommend distributed architecture source codeROS development has many dependencies. Then , Use a command , You can start from YML Create and start all services in the file configuration.It supports: starting/restarting/status of Docker daemon killing/removing Docker containers, images pruning images, volumes, networks. Script to make your life easier with Docker daemon on MacOS. The Docker for Mac application creates a launchd service:mac-docker-go. Attempted setup with Docker for Mac. Then set the Virtualbox VM up to run at boot. Instead run Docker in a VirtualBox VM, either by creating a plain VM or using docker-machine.
Docker Stop Mac And WindowsDocker-compose.yml The configuration case of the is as follows ( Refer to the following table for configuration parameters ): exampleLinux We can go from Github Download its binary package to use , The latest release address :. Last , perform docker-compose up Command to start and run the entire application. Use docker-compose.yml Define the services that make up the application , So they can run together in an isolated environment. UsageUse Dockerfile Define the environment of the application. COPY requirements.txt requirements.txtCopy requirements.txt And install Python Dependencies. Python Packages can be compiled to speed up. RUN apk add -no-cache gcc musl-dev linux-headers: install gcc, In order to be like MarkupSafe and SQLAlchemy And so on. ENV FLASK_APP app.pySet up flask The environment variable used by the command. 4、 Use Compose Command to build and run your applicationIn the test directory , Execute the following command to start the application : docker-compose upIf you want to execute the service in the background, you can add -d Parameters : docker-compose up -dSpecify this yml Obedient compose Which version was made. Redis: The redis Service usage Docker Hub Public Redis image. This sample service uses Flask Web The default port for the server 5000. Then , It binds containers and hosts to exposed ports 5000. CMD : The default execution command provided by the container is :flask run.Create a test directory named docker-compose.yml The file of , Then paste the following : docker-compose.yml The configuration fileThe Compose The file defines two services :web and redis.Web: The web Service usage from Dockerfile Images built in the current directory. Working directory in the image. Cap_add:Specify the parent for the container cgroup Group , It means that the resource limit of the group will be inherited. Add or remove the kernel functions of the host host owned by the container. Target: Multi tier build , You can specify which layer to build. Labels: Set the label for building the image. Args: Add build parameters , This is an environment variable that can only be accessed during the build process. /dir/Dockerfile The constructed image : version: "3.7"services:Perhaps , As an object with a path specified in the context , And optional Dockerfile and args: version: "3.7"services:- "com.example.description=Accounting webapp"Dockerfile: Specifies the Dockerfile file name. In the following example , Start. Container_name: my-web-containerDocker-compose up : Start services in dependency order. Command: Specify a custom container name , Instead of the generated default name. Acrobat update for macVersion: "3.7"services:Endpoint_mode: How to access cluster services. Only in swarm Only in mode. Specify the configuration related to the deployment and operation of the service. Version: "3.7"services:Be careful :web The service will not wait redis db Fully activated And then it starts. In the following example ,web stay db and redis Stop before. In the following example ,docker-compose up web It will also create and launch db and redis.Docker-compose stop : Stop services in dependency order. All requests will be automatically polled to get the cluster ip One of the list ip Address. Endpoint_mode: dnsrr# DNS polling (DNSRR). All requests will pass through this virtual ip Arrive at the machine inside the cluster service. Resources: Configure restrictions on server resource usage , For example, the above example , To configure redis What is needed for cluster operation cpu Percent of and Memory usage. Replicas:mode by replicated when , You need to use this parameter to configure the number of running nodes. The illustration : The yellow square in the figure below is replicated Operation of mode , The grey square is global Operation of mode. Global: Global Services , The service will be deployed to each node of the cluster. Replicated: Replication services , Copy the specified service to the cluster machine. On the container labels( Follow deploy Peer configuration ) Cover deploy Under the labels.Mode: Specify the mode of service provision. Parallelism: Number of containers rolled back at one time. Condition: Optional none,on-failure perhaps any( The default value is :any).Delay: Set how long to restart ( The default value is :0).Max_attempts: Number of attempts to restart the container , Exceeded times , Then don't try again ( The default value is : Keep trying ).Window: Set container restart timeout ( The default value is :0).Rollback_config: Configure how the service should be rolled back if the update fails. Restart_policy: Configure how to restart the container when exiting the container. One of them continue perhaps pause( Default pause). Delay: Waiting time between rollback of each container group ( The default is 0s).Failure_action: If rollback fails , What should I do.
