Hey so I apologise here, I made a typo when I was POSTing the original image, if you look at this point
ruclips.net/video/ctmhYJpGsgU/видео.html
You will see I do something like `curl -vv localhost:9090/images/1/test.png -X POST --d @test.png` the `-d` in curl will post data BUT it will do so as plain text. To upload binary files like images in curl you need to use the ``--data-binary` flag instead.

Please continue this channel. It's the best channel for these types of contents

I really enjoyed it so far,
Thanks!

[@SwimmingInSeas]

Thanks for doing these videos - you're a great teacher! I don't often have the inclination to keep writing code after spending all my workdays writing python, but will happily put on one of your videos while cooking / breakfasting at the weekend, and then have a play. Much appreciated!

[@mohammedbadusha5353]

Hi Nic ..Daily i am learning from your videos. Thank you once again

[@bolajiolumide1378]

Thanks so much Nic, I have learnt a lot and I keep looking forward to the new uploads.

[@rogvids]

The problem is off camera code change :-(

[@sovrinfo]

Awesome, Big Thanks!

[@vishnuvardhan9847]

Thanks for sharing knowledge. When we should define pointer fields in struct type golang ?

[@fresonn]

Will there be a video about the deployment of Go microservices?

[@NicJackson]

Yes I will be looking at that in an up and coming video

[@topsu80]

Thanks for these videos, really good series.
However I think there is some issue with the code. The downloaded image size is only 446K, while the original image size is 816K. Any idea why? I was doing the same code on my computer and first thought I made some error, but looking at 28:00 in the video it shows the image size of the downloaded image test2.png is 446K and in GitHub the frappucino.png is 816K.
Edit: uploading the file with following command works: curl localhost:9090/images/1/test.png --data-binary @test.png

Sorry for the confusion here, I have updated the readme, and I am going to pin your comment to the video.

[@topsu80]

@@NicJackson Thanks for the reply. I managed to get it working now by using `curl localhost:9090/images/1/test.png --data-binary @test.png` to upload the file. :D
Keep up the good work!

[@vtvvnha2230]

the sound is smaller than other videos

[@NicJackson]

Sorry about that, my Mic cable is picking up loads of static. I have a new cable coming

[@PlanetoftheGaming]

I'm having a little problem, the handler work perfectly, but once i get the images back my pc can't open them anymore, does anyone have the same problem?
Great series

[@NicJackson]

Hi there, sorry I made a typo in the video when executing the curl command..

[@eddwinpaz]

can you also teach plz. how to do when arriving on kubernetes how to do multiple services on a single ingress and path them on different url paths. would be cool.

[@NicJackson]

I think I will change the format, I will try to do a weekly Building Microservices but do a mid week topic like ingress which is related but not directly so to the material.
