learning-cloudnative-101's Issues

let's split the container and kubernetes module

Change start page for learning module

The start page should be this one
https://ibm-cloud-architecture.github.io/cloudnative-learning-101/cloudnative-learning-101/1.0.0/Cloud_Native_Module/Cloudnative_Overview.html

Update start_page https://github.com/ibm-cloud-architecture/cloudnative-learning-101/blob/master/site.yml#L7

Delete the current index.adoc that has the prereqs.

complete lab 5: helm

Do a simple helm deploy using the same app from previous labs.

https://github.com/ibm-cloud-architecture/cloudnative_sample_app/tree/Basic-Tutorial/chart/cloudnativesampleapp

helm template chart/cloudnativesampleapp/ -v replicas=2 | oc apply -c
oc expose service

this might be a cool first day of Cloud Native Bootcamp

The bootcamp was a great firehose of info. Now that I've had time to practice what I learned and have contributed back to image-ibmcloud-dev I reflect back and think this might be a cool first day of Cloud Native Bootcamp

Install Docker

create oc url variable with you cluster url
read ocurl
create oc token variable, -s hides it and doesn't even show up in history
read -s octoken
Show how quickly a container helps you begin working without all the machine configuration
docker run --env ocurl=$ocurl --env octoken=$octoken -it --rm --name ibmcloud-dev quay.io/ibmgaragecloud/ibmcloud-dev

~ $ igc --version
1.23.0
~ $ tkn version
Client version: 0.20.0
~ $ oc login --server=$ocurl --token=$octoken
Logged into "https://****-*.us-south.containers.cloud.ibm.com:31185" as "IAM#*****@***.com" using the token provided.

You have access to 73 projects, the list has been suppressed. You can list all projects with 'oc projects'

Using project "default".
Welcome! See 'oc help' to get started.

startupProbe is missing in the list

I have found that:
https://cloudnative101.dev/lectures/kube-observability/#liveness-and-readiness-probes

...three options are named but only two listed:

The kubelet can optionally perform and react to three kinds of probes on running Containers:

livenessProbe: Indicates whether the Container is running. Runs for the lifetime of the Container.

readinessProbe: Indicates whether the Container is ready to service requests. Only runs at start.

I guess the startupProbe is missing here.

(anyway: I am a big fan of cloudnative101.dev! really helpful!)

Fix Lecture Cloud Native Previous and Next links.

At the end of the Lecture :: Cloud Native Previous and Next topics needs to be updated as they are taking you respectively to Perquisites and Cloud Native App Dev of Concept :: Cloud Native.

Update minikube tekton lab sample to use LoadBalancer

Since we are using the same sample app in argocd lab, we should not patch it from NodePort to LoadBalancer, we should tell user to use minikube tunnel and access tekton dashboard via LoadBancer IP and also the deployed app at the end no NodePort need it.

Add an entry in to the global website

Add entry for the learning module to the site https://ibm-cloud-architecture.github.io/deliverables/cloud-native.html

Lab - IBM Cloud Container Registry missing CR login

I found that at step 3, I wasn't able to build the image after I had cloned it.
My fix was to login to the container registry after step 2 using $ ibmcloud cr login

https://cloudnative101.dev/lectures/containers/activities/ibmcloud-cr#create-a-new-container-registry-namespace

implement short .dev url

Update the Dockerfile for Spring Sample to use Liberty from CloudPaks

Update the dockerfile with this one https://github.com/ibm-cloud-architecture/cloudpak-for-applications/blob/spring/Dockerfile

Request to add links to Cloud Architecture Center from Cloud-Native Developer Bootcamp course

This is a request to add links to the following architecture pages from the Resources section of this course:

Edit this Page is not working on website

When visiting any of the pages https://csantanapr.github.io/cloudnative-learning-101/cloudnative-learning-101/1.0.0/index.html

There is an Edit this Page link on the top right of the page it doesn't have the correct reference to github url.

circleci is doing a checkout of the source code and building with source from local files on disk vs. an url reference.

If there is a way to specify in the site.yaml an override on how antora generates this link will be awesome to fix

rename the repo and website for the learning module

Rename repo to learning-cloudnative-101
Update site.yaml
Update antora for the url cloudnative-learning-101 -> learning-cloudnative-101
Check Circle CI
Update the README

Lab 4: Scale and Rollout Updates

Lab 3: rename to Deploy app on Kube

Lab 4: Update app on Kube

Scaling out your app

Show the current deployment with 1 pod

oc get deployment greetings-deployment

Let's scale to 3 pods

oc scale deployment greetings-deployment --replicas 3

Update your app

In another terminal watch the status

watch -d oc get deployment greetings-deployment

Update the deployment to new image tag ibmcase/greeting:2

oc set image deployment/greetings-deployment greeting=ibmcase/greeting:2

Get the status of the rollout

oc rollout status deployment/greetings-deployment 

Monitor the app for no down time

while loop curl $url

The links in the agenda in the course overview don't work

Here

https://cloudnative101.dev/course-overview/
https://github.com/ibm-cloud-architecture/learning-cloudnative-101/blob/master/src/pages/course-overview/index.mdx

add a dev-site.yaml for antora and update gulp

this allows to do dev locally with live reload

Update description of Jaeger in OpenShift & Kubernetes Activity

Within the Distributed tracing section, there is an Activities table with some labs: https://cloudnative101.dev/electives/dist-trace/#activities

The description and link name (the link is actually correct) does not seem to match the activity topic.
That is, the activity is called "Jaeger in OpenShift & Kubernetes" while the description says "Implementing Istio on Kubernetes & OpenShift" and the link name is "Istio Kubernetes"

cf migrations guide should be embedded not linked

To keep a good UX for the learning module is better to have the tutorial embedded instead of linked out.

Add Operator opening

Insert an operator intro paragraph
Before intro of the 2 examples https://ibm-cloud-architecture.github.io/cloudnative-learning-101/cloudnative-learning-101/1.0.0/Kubernetes_Module/operators.html#_ibm_cloud_operator

and link to the getting started with operator framework
https://github.com/operator-framework/getting-started

code snippet need colors

The website has some labs that have code snippets like java or yaml, it would be good to configure this snippets to be render with color based on programing or markup language

Example using xml https://csantanapr.github.io/cloudnative-learning-101/cloudnative-learning-101/1.0.0/Cloud_Native_Module/Lab1.html

LogDNA video not available

It seems like the video about LogDNA on this page is not available on YouTube anymore.

rename navbar menu items
