--global services: the swarm runs one task for the service on every available node in the cluster.(一个节点,一个服务,共同组成一套服务) 3. Task && Container A task is analogous to a “slot” where the scheduler places a container, 是swarm中的原子调度单元,对应运行在一个service中的单个cont...

docker swarm init 1. 部署我们的app并给它命名: docker stack deploy -c docker-compose.yml getstartedlab 1. 这样一个主机上就运行了一个镜像(image)的五个实例(contianer) 显示我们的服务: docker service ls 1. 在服务中运行的单个容器,我们称为任务(task),下面命令列出我们服务的任务: ...
docker docker是swarm-manager的主机名 通过docker node ls查看各节点现在的状态: 现在swarm-manager node的状态是Drain状态,Drain表示swarm-manager已经不负责运行service,之前运行的那个service会如何处理呢? 通过docker service ps 查看一下: swarm-manager 上的副本已经被shutdown了,为了达到5个副本数的目标,在docker...
Once you have deployed a service to a swarm, you are ready to use the Docker CLI to scale the number of containers in the service. Containers running in a service are called tasks. If you haven't already, open a terminal and ssh into the machine where you run your manager node. For...
When you have deployed a service to your swarm, you can use the Docker CLI to see details about the service running in the swarm. If you haven't already, open a terminal and ssh into the machine where you run your manager node. For example, the tutorial uses a machine named manager1...
