In case anyone else is having the issue where Air is not reloading on a Windows machine, inside the .air.toml file you must set " poll=true " for the changes to be picked up in real time. Great video though!

your go tutorials are the best and simplest to understand! can't wait to see more go tutorials in the future~
Aw, thank you for the encouragement!
@@DivRhino yw~ also, would it be fine to ask for suggestions on other go tutorials? in particular, i would like yo see a rest api tutorial that uses gorilla mux, since it is a very popular go library for making near-vanilla golang rest apis. also, making a TUI application using charm bubbletea, in which i'ce heard they are a great library for making cool TUI applications~ just some suggestions, thankss
@@cindrmon Thanks for the suggestions. I've played with bubbletea a couple of times in the past, so I can definitely consider making a video about it.
I'm a little hesitant to make a video about mux as there are many good ones out there already.
I appreciate your feedback.
this is 🔥, very nicely presented
thank you for this tutorial
Thank you for watching, I appreciate you being here!
This is extremely well done! The instructions are clear and concise. Great job!
Thank you so much for watching!
I’ve just finished your video “Learn to Code by NOT Doing What Everyone Else Does”. Great advice. Looking forward to seeing your channel grow 🙏✨
@@DivRhino Glad you like it, thanks! I'll be going through all of your videos. It's taking me a while to get comfortable with docker. =\
@@handmadegamesdev I hope you find the videos useful ☺
you are indeed gifted at teaching. although i have some problems with my computer, this video helped me understand working with docker better. Thank you so much, you definetely don't have enough credit for what you do.
What a thoughtful and encouraging comment 🥰 thank you, I appreciate you being here 🙏
Excellent!
Thank you for being here! ✨
Excellent presentation - no adjective - no adverb - straight to the point with facts and monotone narrative presentation... Thank you for sharing your experience
Thank you for your support! Happy to have you 🙌
I know how to use docker but i didn't know this kind of magic is possible with it! Air is amazing.

Subbed. Great content
Just a suggestion would be to make the text size a bit larger so it's easily visible in the video
Thank you for being here! And thanks for the feedback. I’ll make the text bigger next time. 🙏
Amazing, Following closely

Thank you
Thank YOU for being here! 🙏
lovely
Thank you 🙏
this is great, one suggestion is zoom in more into the editor
Thanks for the feedback. I’ll keep this in mind for all future videos 🙏🙏
Hey Div Rhino! Long time. wb
Hey Big Squeak! Thank you 🥰
great video, i'm very appreciated with your dediation that you put into making these videos. And it can be more wonderful if there is any solution for not hot reloading while using windows ?
Hello there, thanks for leaving a comment. Several Windows users have reported similar issues with hot reloading when using docker. Here's a link to a potential workaround I found in the air repository:
github.com/cosmtrek/air/issues/190#issuecomment-999254716
15:12 log.Fatal() is like .Println() followed by os.Exit(1) so no need of os.Exit(2)
Cool. Thanks 🙏
Good tutorial, for the next one try to zoom to the desktop.
Thank you for the feedback 🙏
Should I run this command (docket compose build) whenever I updating docker-compose.yml or Dockerfile?
Thanks for your question. If you’re adding new steps to your Dockerfile, you should run the build command. Images are static once they are built and they do not automatically update themselves when new instructions are added. So every time you add something new to the Dockerfile, you’ll want to rebuild.
docker-compose is a tool that allows you to work with multiple Dockerfiles in the one project. You don’t usually need to rebuild an image when you change the config there. But sometimes you may need to restart your server.
I hope that helps 🙏✨
I have a go project and I was making a docker image. It build successfully but when I tried to run it, .env file was not actually copied in the docker image. How can we copy the file name starting with dot.
Have you added a COPY instruction to your Dockerfile to copy over the .env file?
I have an issue "too many open files" when run docker compose up, can you help me! Thanks
Hi there! Thanks for your comment. I'm sorry to hear that you're having trouble. I found an answer on stackoverflow that may help you out:
stackoverflow.com/a/43265189
at 4:17 the go.mod file doesnt appear on my project board... i can see it with "ls" but i cant see anything i create in the container
Hi there! I'm sorry to hear you're having trouble with this. Are you by any chance using a Windows machine?
air is not hot reloading, my vscode has the auto save feature, I tried disabling it but still is not working. Any ideas?
Hello there, are you on a Windows machine? I have seen other people online having issues with using the air package in Docker on a Windows machine. I am not sure how to use docker on Windows, unfortunately.
@@DivRhino yes I am on windows :( any alternatives?
@@manuelillanes1635 I found this open issue in the Github repo and it looks like someone there has come up with a solution.
Give it a try, maybe?
github.com/cosmtrek/air/issues/190#issuecomment-999254716
I can't connect to the db, := failed to connect to `host=localhost user=postgres database=`: dial error (dial tcp [::1]:5432: connect: cannot assig432: connect: cannot assign requested address), i created a new one, but doesnt worth...
Hey.... hot reload it not working in docker windows 11 :(
Hello there, unfortunately this seems to be an issue that others have also faced when using air with docker-compose on a Windows machine. 😥
DB CONNECTION DIDN'T WORK - failed to initialize database, got error failed to connect to `host=db user=test database=test`: failed SASL auth (FATAL: password authentication failed for user "test" (SQLSTATE 28P01))
Sorry to see that this isn’t working for you. Without seeing your code, it would be difficult to see where the issue is occurring. I have linked the text tutorial and the finished code in the video description. It may help to compare your code with that to see if you can spot the differences.
Same here, any solutions?
Did you find a solution? I'm having the same issue.
@@manuelillanes1635 I solved it removing volume and running prune to clean all local data related to volumes.
this is need to install golang in linux first?
Hello! You do not need to have Golang installed first. But you do need to have Docker installed and running to be able to follow the tutorial.
@@DivRhino thanks for the reply, so we can configure for go specific version from dockerfile right?
@@muhamadrifqi5709 Yes, that's right. Once you have docker installed on your machine, you will use the Dockerfile to specify which Golang version you want to install.
how to check database ?
Hey there, thanks for your question. You can use a database client like Postico, Navicat or DBeaver to check your database in a GUI.
You can also use psql if you prefer to work in the terminal.
You should make the fonts bigger, it is hard to read.
👍✨
how worck withot GORM?????
If you don’t want to use an ORM like GORM, you can write SQL.
Can you do a urfave2 tutorial?
Hello Marvin, good to see you again. Thanks for leaving a comment. Do you mean urfave/cli?
@@DivRhino oh you remember me. I’m still learning go and need help with api lol. Yes urfave. Cli
That will be a big help. Thank
please increase font size in the video for your blind homies
Thank you for the feedback! Yes, unfortunately many people struggled with the small font size, sorry about that. I will make it bigger for all future videos. 🙏🙏
use a larger font. i need my eyes
Okay
Very well explained. Could you please increase the font size of your IDE ? It's hard to see on the mobile.
Thank you for watching! And I apologise for the small IDE text size. I'll keep mobile in mind for future tutorials. I appreciate the feedback 🙏
@@DivRhino thank you
