DOCKER DESKTOP IS SHUTTING DOWN SOFTWARE

In software container terms, we can say, вЂњ I would like a pod named web, in which there should be a single container, that will run the nginx image.вЂњ If it doesnвЂ™t exist, it will build it if there is already one but itвЂ™s green with red doors, it will paint it for us if there is already a container of the right size and color, Kubernetes will do nothing, since what we haveВ already matches what we want. In other words, we can say, вЂњ I would like a 40-feet long blue container with yellow doorsвЂњ, and Kubernetes will find such a container for us. We canвЂ™t say, вЂњrun this container.вЂќ All we can do, is describe what we want to have, and wait for Kubernetes to take action to reconcileВ what we have, with what we want to have. Kubernetes is a declarativeВ system (by opposition toВ imperativeВ systems). ThatвЂ™s what happens here: when we tell Kubernetes, вЂњ create me some NGINX!вЂњ, weвЂ™re really saying, вЂњ I would like a pod, in which there should be a single container, using the nginx image.вЂњ # pod-nginx.ymlДЄlright, then, why donвЂ™t we just have a pod? Why the replica set and deployment? Declarative vs imperative From a network perspective, all the processes in these containers are local.Д«ut we can never create a standalone container: the closest we can do is create a pod, with a single container in it. A pod is just a group of containers (it can be a group of oneВ container) that run on the same machine, and share a few things together.ДЇor instance, the containers within a pod can communicate with each other over localhost. In Kubernetes, the smallest unit of deployment is not a container itвЂ™s a pod. To extend that confidence to the release process, your deployment operations need to come with a safety belt. In fact, a lot of people end up thinking that if we had been tasked with designing the system, they would have come up with something quite similar!Д¬ontinuous integration gives you confidence in your code.

This is the kind of situation where at first glance, we wonder вЂњ whatвЂ™s the point?вЂњ, but once we get the full picture, weвЂ™ll understand the role and purpose of each component.

In short, these Kubernetes objects ensure that you can progressively deploy, roll back and scale your applications without downtime. I just wanted a container! Why do I get three different objects? Note: we can ignore the serviceВ named kubernetesВ in the example above that one already did exist before our kubectl runВ command.

a deploymentВ (called webВ in this example),.

Instead of getting aВ container, we got a whole zoo of unknown beasts: NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE Service/kubernetes ClusterIP 10.96.0.1 443/TCP 46s NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE LetвЂ™s look at what happens after running a very basic kubectl runВ command: $ kubectl run web -image=nginxДЄlright! Then we check what was created on our cluster, and вЂ¦ $ kubectl get all Folks who have experience with Docker tend to compare it to docker run, and think: вЂњ Ah, this is how I can simply run a container!вЂњДЄs it turns out, when one uses Kubernetes: One of the first Kubernetes commands that we learn and use is kubectl run.

Or even 8042, 8142, 8242.ДЄs I said, I wonвЂ™t go with this solution, but just too curios.Ready to deploy that app youвЂ™ve just вЂњdockerizedвЂќ? HereвЂ™s all you need to know about Kubernetes deployments to deliver your containers to production.Д®ditorвЂ™s note: This is a guest article by JГ©rГґme Petazzoni, a former Docker engineer, speaker and creator of aining. However, I wonder why solution from this guy works when it uses ports 9042, 9142, 9242, but doesвЂ™t work when I set 27030, 27031, 27032, for example. Anyway, IвЂ™ll go with your solution because I like it more. Now I want to add replica members and IвЂ™ll execute the next: rs.initiate(ДЄnd finally add the hostnames to the hosts file вЂњhashвЂќ : BinData(0,вЂњAAAAAAAAAAAAAAAAAAAAAAAAAAA=вЂќ), вЂњerrmsgвЂќ : вЂњno replset config has been receivedвЂќ, If I execte rs.stats() it will get me the following:

IвЂ™ll create volumes in production instead biding, but not important right now.ДЄfter I execute docker container ls I can see the following: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESД¤de461506c94 mongo:4.4.2 'docker-entrypoint.sвЂ¦' 18 seconds ago Up 16 seconds 0.0.0.0:27031->27017/tcp mongo-2Дўf6ff3f6cbef mongo:4.4.2 'docker-entrypoint.sвЂ¦' 18 seconds ago Up 16 seconds 0.0.0.0:27032->27017/tcp mongo-3ДЁa467ad33809 mongo:4.4.2 'docker-entrypoint.sвЂ¦' 18 seconds ago Up 16 seconds 0.0.0.0:27030->27017/tcp mongo-1 This is how my docker-compose.yml looks like: version: '3.7'Д¬ommand: /usr/bin/mongod -bind_ip_all -replSet rs0 -journal -dbpath /data/db -enableMajorityReadConcern false
