Become a Docker Swarm Expert in just 20 minutes

In this video, I have explained how to Orchestrate a Docker Container with Docker Swarm.

Agenda for this Video:
What Is Docker Swarm?
Why Use Docker Swarm?
Docker Swarm Setup
Starting The Docker Swarm Service
Docker Swarm for High Availability
Load Balancing Docker Containers across multiple Docker Worker nodes
High Availability by Scaling Up the Docker Swarm Services
How to remove the Swarm workers

What Is Docker Swarm?
Docker swarm is a container orchestration tool, meaning that it allows the user to manage multiple containers deployed across multiple host machines.

Why do we use Docker Swarm?
Leverage the Power of Containers
Docker Swarm Helps Guarantee High Service Availability
Automated Load-Balancing

As a prerequisite, you need to have Docker installed.

Docker Introduction:

Docker installation from Scratch:

OMG; everyone else drones on, and doesn't really do anything. Your presentation is top-notch and pragmatic. I appreciate you!

[theshile]

Really good. Simplest theoretical explanation and then actual implementation.

[okey]

where do you get such machines with ip that you accessing on terminal?

[alekhgupta]

Solid knowledge and excellent teaching skills.kudos to you for a crisp and clear explanation 😉

[yogeshdharya]

Swarm Looks quite simple to me now, thank u Akash 😄

[Virtualstar]

i have no words .. simply osm ... best excellent

[satheeshreddy]

Simply super bro.its easy to understand and we can crack the interview point of view.

[ravindrakumaryadav]

Thanks for this video. It was easy to understand 🙂

[mithileshpandey]

how we can deploy the code changes in docker swarm manually ?

[okey]

but right now, you are inside a master node and crearing all the applications.. But if the docker swarm cluster is somewhere else, will i be able to use it from my laptop?
ie, for kubernetes we use kubectl to login right

[MarkDeibert]

So good explanation, but for a couple beginning parts. What are the nodes that you started the video with? 1 "master" and 2 "workers". What are those containers? Jenkins? Other?

[sudheersid]

Hi Nice Teaching,
I have installed Elasticsearch and Kibana in master and slave
How we do with HA can you pls guide me

[samansaeedi]

Hi. my very first question is, where is the environment you login at the beginning at 3:35? how are the machines built? how to set the IPs? I know I have low info on it but there s lack of explanation on that part.

[durgaprasadpj]

HI akash, I have seen your video and it was clearcut explanation. but my doubt is how to setup postgresql streaming replication setup across different servers with HA

[OnesimusX]

How are volumes / storage managed? What if there was data on the node that was drained? Would that be replicated as well?

[mahic]

Thanks for your video.
How we can add the deleted (worker) node from the docker swarm back to the Docker swarm node list? Let's say we forgot to save the docker swarm token id required to add the nodes into the list
Thanks

[ghodaketushar]

Hi Akash, what if my manager node goes down? Will my worker node be promoted as a manager? If yes then which IP I should use to access my application? Will there be a virtual IP? if not then how will it help me to achieve HA?

[sandeepbharmoria]

Hi, I need help in creating elastic search cluster in docker swarm in 4 hosts, can u please guide me with any example?

[rizalnoviandy]

Very good video. Can the docker swarm manage node for load balancing? I mean by set the priority, so when 1 node is drain/down it will be handled by spesific node. I really want to know the answer. Thankyou

[sreekanth]

Hi Akash, I am using 1master and 2 worker nodes when i make master drain i am not able access jenkins server with the public ip of the master even containers are running in worker nodes? can you please help me out of this ASAP
