Add some missing questions. The main content of this chapter: use constraints to specify service constraints. Service mounts use local volume. The Elk Log platform uses the Gelf log driver to collect logs. 1. Specify service constraint In the previous chapters, we created the Registry service, which was executed on a node by the Swarm automatic dispatch definition. In that case, if we restart the service, registry services may be started with random n

1. Swarm is a scheduling framework developed by docker. (Found on the Internet) 2.Server Load balancer: Docker is called ingress load balancing ). It works by listening to published service ports on all worker nodes. When the service is called by an external system, the node that receives the traffic will use the internal DNS service provided by

if the container can get more running memory, such as Redis. Machine failure can automatically deploy the container on the faulty machine to other nodes. If the cluster adds a new machine, rebalance the container's allocation. If the container fails, restart it. ... Now that you understand why container orchestration is needed, let's take a look at the two most popular options and the contrast between them today.Docker SwarmSwarm is the development of native cluster managem

BackgroundPreviously, the service was created on different servers (Docker host) using Docker swam, and the container between them was communicated through overlay network. Yesterday due to the company's network maintenance, one of the servers (we referred to as manager node) due to maintenance, temporarily unable to connect (probably lasted 6 hours). Come back today, we found that the communication between
