Cheers from brazil, all of your content is just amazing thanks for support the community <3

I enjoyed the course and learned a lot from it. The content is well organized and focused on practical examples. Thanks a lot for helping many people like me.

Thanks for this valuable session !! Looking forward to go through K8s tutorial.

Thanks a bunch, nana. This lesson is amazingly clear. It's not possible to put a price tag, thanks a ton for giving it free.

Thank you Nana for this tutorial, I ran into an error while following the instruction on mongo-express, the container would shut down by itself and when i check the logs for mongo-express, it says " (node:8) [MONGODB DRIVER] Warning: Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
"
Any one else has this issues? at https://youtu.be/3c-iBn73dDE?t=5051

Hello Nana, I really appreciate your work in creating this course. This is epic and exciting to watch. By far the best docker course on Youtube. I am really thrilled.

Thank you very much for such a knowledge tutorial. One of the best tutorial, I came across.
Thanks again

Amazing Content. i have seen lot of videos but was not getting anything, but the way you explained it was amazing. Thanks for this great content.

It's safe to watch at 1.6x speed..

Thank you so much Nana, I've learnt a lot from your video. Before this, I jumped into another one which was suggested by Youtube and that guy provided non-sense tutorials, he just tried to sell his course, completely waste of time.
I've clicked on all google ads in this video, hope this helps a bit to your channel.

Could you share the codes used for the labs

how can we manage these volumes on aws

Thanks for this great tutorial. When run the image, those mongo & mongo-express will be run first automatically? Noticed that we only need "node server.js" in the docker-file

the program is very easy to understand

Could anybody explain to me what docker ps -a | grep my-app does? And what is grep? Thank you in advance

fantastic course, thank u Nana!

What is the difference between docker stop, docker kill and docker pause command ?

lets say if we use weblogic then we will have the image of the weblogic installed, i am assuming that we will just have to deploy the .ear or .war file and we will configure the weblogic the same way we do it now like configuring the data base etc. is this true statement or false?

Great Session !!!!!!!

Hello! I am wondering why are my logs showing differently than in the video? They are not structured and line starts with {"t":{"$date":"2022-04-30T14:48:58.969+00:00"},"s":"I", "c":"STORAGE", "id":22430… and so on.

FYI: Your MongoDB example worked up until the release of MongoDB 5.0 on July 13, 2021. For anyone using a cpu that doesn't support the AVX instruction, they will need to install MongoDB 4.4.6 (or earlier) to follow along with your tutorial (1:20) – change mongo to mongo:4.4.6. The newest version of docker-compose is v2.4.1 and it's now accessed through "docker compose" rather than "docker-compose"

Additionally, your YAML file (1:34:55) no longer works due to <reasons?>
To get it to work, the mongodb image needs to read –

image:mongo:4.4.6

And add the following three lines to mongo-express:

depends_on:
– "mongodb"
restart: unless-stopped

High quality content Nana, thanks for the dedication and sharing.
Just one comment here in april 2022, at timestamp 1:35:00 I had to add the "restart: always" entry on the mongo-express service section of the mongo.yaml Compose file to be able to get express connected.

Thanks for such an excellent content!

What a fantastic course.

Thanks a lot Nana, for the content, efforts and simplicity of the course. Kudos.

Thank you!

mongo-express container is crashing since the mongo database service is not yet up in the mongodb container while using docker-compose. I have tried using depends_on but it is till crashing. Any help?

Hello, Thanks for such a good tutorial. I am facing one issue while running 'docker run postgres:9.6' in ubuntu :-

Status: Downloaded newer image for postgres:9.6
Error: Database is uninitialized and superuser password is not specified.
You must specify POSTGRES_PASSWORD to a non-empty value for the
superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".

You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
connections without a password. This is not recommended.

See PostgreSQL documentation about "trust":
https://www.postgresql.org/docs/current/auth-trust.html

Can you please suggest some solution. I am using 'Ubuntu 21.04'. Thanks .

One of the best docker tutorials. Thank you

Very well explained this course in step by step, Thank you Nana for your efforts and sharing with us.
