How to scale docker containers using Nginx as reverse proxy and load balancer

[@teetanrobotics5363]

Please include this in the "Production ready server" playlist. As horizontal auto-scaling is also a very useful feature in the production ready server. Amazing content. Thanks.

[@aspirinemaga]

Man what a perfect and straight explanation. thank you so much for your efforts! you are a legend

[@suman6327]

Such crisp & clear explanation. Thanks a lot.

Still waiting to see the 1000 container version as promised in the thumbnail .... :)

I couldnt figure it out and you saved me hours of work thanks!!!

Since there's no upstream definition in the nginx conf, we're pretty much stuck to a round-robin type of configuration with this setup right?

[@yasser.dev7]

Pure Gold 🪙, Thank you man!

[@namcaohai2221]

Thanks, will do!

Does this also work with JWT Auth containers? Or will this mess up the JWT auth?

[@johndoe-g6q]

Hi, when i tried setting it up.. it only routes between 2 containers instead of all containers (in my case 5). why is it so?

[@ashutosh887_]

Truly a Gem! ✨✨✨

[@someonenotlikeyou]

I have been scratching my head the whole day trying to figure out why my nginx wasn't working. I wasn't using docker-compose.yml; instead, I was creating separate containers for each server instance. On top of that, I was editing the main nginx configuration file (/etc/nginx/nginx.conf) instead of changing the virtual host configuration file (/etc/nginx/conf.d/default.conf) as you did. After watching your video, I figured out two issues. First, my containers were not communicating with each other because I hadn't created a custom network for them. After doing that, everything worked fine with reverse proxy and load balancing. Second, I still don't understand what the issue was with using the same upstream to specify the servers and the location with the proxy_pass directive to send them to the servers in round-robin. Maybe it's not a good practice to update the main nginx configuration file directly, but I'm not sure. Can you provide me with some resources to read more about nginx configurations? Thanks a lot; this video was a great help! 💕💕

[@riteshthakur9250]

Great tutorial sir as always you make really good tutorials.

[@mafiacodes]

Thank you very much!

[@digvijaysinghthakur2903]

man thanks for great content

[@mehmetbilentr]

Simple and quite usefull explanation, thank you.

[@silverskull4140]

In npm ci, ci stands for clean install.

[@kks2105]

Great explanation, thank you. I was just wondering, if we are running in same machine we can use cluster module as well right? The nginx with auto-scaling may become prominent when using multiple standalone servers, isn't that right?

[@gupta05]

I am getting error while running docker compose up --scale api-2 - curl localhost:3000 does not round robin between 2 containers alternativly although both containers are created as seen in docker ps. what could be the issue. please help. thank you

[@medievalogic]

You're not using nginx here to load balance. You're using docker to load balancer. Tge nginx container is just a proxy in this setup.

[@salishsath530]

how it will auto scale

[@SamyarBorder]

Wow that was awesome 👌 thank you

[@samatzhussipov1139]

Worker conrainers limited by server thread? Example: server - 4 core 8 thread 4 ram --> I can create only 7 worker container + 1 for nginx ?

[@sathithyayogi99]

may i know what terminal you are using, i am also want suggestion like that

[@mafiacodes]

oh-my-zsh + spaceship prompt + autocomplete plugin

How we scale up the Nginx container so that there are two replica of Nginx?

[@barcasnerd]

How can I configure this nginx to add a new distinct service with a different server location, for example /new

[@arthurmelo88]

there is a way to create a rule for nginx to fire up more docker containers based on requests demand?

[@vishaldharmawat]

Amazing Video :) Really helped, just one correction, I believe CI stands for Clean Install. Please correct me if I am wrong.

[@13odman]

Correct

[@mimahmed95]

Superb. Thanks for your hardwork.

[@eL3M3nT4LisT]

Thank you man you are the best

[@mirzaleka9319]

Well explained. Thank you!

[@sajjadmazhar1666]

what theme are you using?

[@ilyaslabukarov5959]

Thank you very much! This video helped me a lot.

[@georgestatefield]

What a nice lesson!

[@leamon9024]

Awesome explanation. Thank you.

[@Bengali4]

Great video, is it possible to configure de reverse proxy to request server from another machine with different IP? Like configure an upstream cluster in nginx

[@samansaeedi102]

awesome. but you didnt say about load balancer!! is it in another video?

[@AbdulAlim-zg8vt]

I really liked your command prompt theme. Can you please tell me the theme name?

[@Anubis10110]

Thank you so much amazing video

[@naturevibezz]

Can we use this in a production environment??

[@mafiacodes]

Yup

[@amansarma417]

Sir lets say i have three vps each of dual core processor and each vps will have two docker container running(of same image). How can we load balance and proxy using docker. Since the vps are different they will have different ip and container id how do we link all of them? Do we need to have another vps only for nginx to load balance or just puting nginx in vps1 it will do the job?

[@mohamedsulaimaansheriff9787]

This is not possible

[@ronaldfungss]

great content! thanks a lot!

[@LexPrimost]

Hi ! great video as usual !, is that a normal behavior that you can access the api container by its port without exposing the 3000 port in its Dockerfile?

[@carvalho1990]

Great tutorial, but scaling all those app in the same machine, even with different containers, won`t make so much difference, right?

[@AadiManchekar]

Thankyou

[@milon27]

thank you. how to scale my MySQL database? i am using 1vcpu,2gb ram digital ocean droplet, which contains a node js API and MySQL server, it works fine, but after 10-12 days MySQL queries become slower. how to scale MySQL? i have 50% ram free and only 3-4 % cpu is using most of the time.

[@Mysterious_debris_1111]

Try using cockroach db... It is fun.

[@SavagePlay]

can someone give his zsh theme

[@usama57926]

good video

[@thianesh9097]

Great! Tank you ❤ Hey Bro, I'm scaling a Chatbot where the user's history is preserved. After scaling up I want the users second or forthcoming request to point to the First request Host. I can send the hostname to user and send it back as you shown. Can U guide how to map request to particular host?

[@mr_ehmed]

Best

[@MrCray678]

Bro AWS having less tutorial in KZbin so working with Aws is too hard for who never know about it can we have tutorial about it

[@mafiacodes]

I’ll try to make it Subscribe like share

[@ghostkee5031]

the only non well explained! part is specifying api on proxy_pass and not saying where its coming from or how nginx detect it cuz its a service name not a loadbalancer upstream name

[@BilalShahid-z7y]

wait wait.. npm ci doesnt stand for "continuous integration" it stands for "clean install". make some correction dude.

[@himanshulal97]

I love ❤ you

[@thisismegopi]

npm ci = clear & install

[@mafiacodes]

Imo continuous integration

[@azlk_playz8669]

why u didnt use any orchestration tool? why you made things this complicated??? @yoursTRULY

[@mafiacodes]

You can do that
