when you join the swarm as a worker by specifying the manager ip, the port number that's specified there in the ip is 2376..so thats apparently docker daemon port which may result in an error..this was written on the docker docs page itself..so the docs suggest that we specify 2377 when we do swarm init and then join as worker node with the ip that we will see there..it works like a charm

Hello Raghav Da, This tutorial is really great for a beginner like me but since I am working on docker latest version I can't find docker-machine in my system installed neither was I successful to install it in my system separately, if you can please guide. Also just checking if there is any recent tutorial on docker swarm? Thanks a ton Binita

@RaghavPal

Ай бұрын

1. Docker Machine: - Docker Machine has been removed from later versions of Docker Desktop. However, you can still install it separately if needed. - For macOS, you can use Homebrew to install Docker Machine with the following command: ``` brew install docker-machine ``` - Once installed, you can use Docker Machine commands as usual. Keep in mind that Docker Machine is now merged into the `docker` command. For example: - Instead of `docker-machine init`, use `docker swarm init` - Instead of `docker-machine join`, use `docker swarm join` - For more commands, use `docker swarm --help` 2. Docker Swarm Tutorial: - To get started with Docker Swarm, follow the official [Docker Swarm tutorial] docs.docker.com/engine/swarm/swarm-tutorial/ - This tutorial covers initializing a cluster of Docker Engines in swarm mode, adding nodes to the swarm, deploying application services, and managing the swarm. - If you're new to Docker, it's a great way to learn the basics and explore container orchestration -

Good tutorial! I came here knowing nothing about Docker Swarm and now I feel comfortable to get started playing with it. I have 2 questions/observations: 1) In the case of nginx where 2 nodes were running 14.0.1 and 1 node was running “latest”, will the swarm still operate properly with nodes running different versions? 2) while we have the advantage of redundancy by having multiple nodes, we still have a single point of failure if the physical host fails. Can we create a swarm that spans multiple physical hosts? If so, how?

Thanks. Need quick clarifications, 1) Is it making use of locally available images, when you run 'services'? 2) Can we use 'docker-compose.yml' file for multi image container? If so how to refer it? 2) General Q: If you use 'virtualbox' for node creation, then we have to pay for overhead of hypervisor (this is benefit of not having hypervisor on docker) what typically we compare container against VM right?

@RaghavPal

Hi, 1) when you run, it checks if the image is available locally else pull it from repo 2) yes, we can do it. Refer - docs.docker.com/compose/reference/overview/ 3) Some info on this you can find here - kzread.info/dash/bejne/YplhrcuAeqzPdMY.html

Super tutorial. I have a question. You showed that nginx was running on the three IPs of the docker swarm. To show it, you opened chrome and put the ip in a chrome tab. Then, you created a fourth instance of nginx (scaling up). How can I access that instance from chrome? port 80 should be already occupied, isn'it?

May i know what is the difference between the auto scaling vs load balancing in docker and Using docker swarm we can achieve load balancing and auto-scaling and how we can scale up and down the spring boot application based on requests using docker swarm and May i know docker swarm to achieve client side load balancing

Hi Sai, load balancing is distributing load evenly on the servers automationstepbystep.com/2020/04/28/a-story-what-is-load-balancer/ where as scaling up or down is adding or removing servers based on needs and requirements. You can find some examples for spring boot online

If i open my browser and connect to IP of Worker1 which has 3 containers running, what will happen? are the 3 containers in the worker node automatically load balanced??

Hi Camila Docker Machine is still available and can be installed from the Docker website: docs.docker.com/machine/install-machine/ The docker-machine create command is used to create a new Docker host using a specified driver. The virtualbox driver is used to create a Docker host running in a VirtualBox virtual machine. If you're unable to start the command, it could be due to a few reasons: VirtualBox is not installed on your system. You need to install VirtualBox before you can use the virtualbox driver. The VirtualBox driver is not installed in Docker Machine. You can install the driver using the command docker-machine create -d virtualbox. There may be an issue with your Docker Machine installation or configuration. You can try reinstalling Docker Machine or checking your configuration settings. I recommend checking if VirtualBox is installed and if the VirtualBox driver is installed in Docker Machine before attempting to create a new Docker host.

well done!!
