anyone else get a lil jump scare with the transition music
Hello Andrew, could you please place the option in your video of automatic subtitles also in Spanish?
Thanks in advance.
thanks for it Andrew, is this same as CKA , could you please clarify
Awesome Andrew
Great Video, but the music in the breaks is way too loud 😕
So the 2nd attempt is free of cost?
The guy clearly knows very little about kube, which shows big time in the follow along section. He just copy-pastes from the docs and tries to guess stuff when things don't work. As for the presentation part, he again clearly just copy-pasted things without any understanding, which shows when later he, for example, can't recall what Calico is, even though he talked about it before. And there are many examples of this "I don't remember what it is, it's somewhere in the course". Fucking bullshit. I mean, I understand that it's free content, but maybe you shouldn't teach about things you know nothing about.
For some reason, the Function as a Service topic was skipped without any slides and went to directly on to Knative.
Thanks so much for the material, I am a cloud expert and just got Prometheus certified and now going for KCNA, bought the course cause it really covers what I need. Thanks again 🙂
Video on gRPC I used for a deeper explanation:

hi are the slides shared in this video available somewhere? thanks 🙂
8:36:42 the 'apply' command failed because the minimal-ingress object does not have its definition file stored as annotation. In order to have annotation stored you should have used the –save-config flag in the 'create ingress' command earlier
8:17:49 about the 403 http status code trying to reach EC2 using wget and ExternalName is returned by AWS EC2 because the "Host" header in wget request does not match the ec2 instance public dns name. Instead this is set to the same name of the ExternalName service which does not do any rewrite of the Header. Does anybody know how to make ExternalName still effective in such cases?
8:21:13 jessie is the codename of a Debian Linux release, presumably the one used to build the base image. I know this because I run this on my Raspberry Pi 🙂
Love seeing the Cloud Native Shared Responsibility Model still going strong! Thanks for including Andrew!
I love how he progressively gets more exasperated with k8s in the follow along. Using k8s is such a complicated pain in the ass and this is so relatable!
Are there any other courses that need to be done before diving into this?
Hey Andrew. This free session (and the paid course mock exams) have been really helpful. Thanks to you and your support team for the timely support and for this beneficial course ✌️😃
I've cleared my KCNA exam Alhamdulillah
Do you have a suggestion/video for the CKA exam?
For my bookmark only 1:34:00
