cloud-native-guides's Issues

auto copy/paste click does not work in various places

As an example, in the Swarm module the auto copy-paste for the Inventory.class doesn't work -- clicking in the box doesn't highlight everything.

Prevent admin_user to be set as admin as it fails on gogs

When selecting the admin user and password for the infra services, admin is not a valid value. We need to force a check at the beginning of the execution preventing this.

Download projects in a newly created folder.

In the instruction Download lab project, attendees are instructed to go to cd ~.

They should create a folder, to download the projects.zip, otherwise their home folder will become a mess.

[continuous delivery module] change cd for pushing wildfly swarm

current docs say
cd labs/inventory-wildfly-swarm

But if user has changed their PWD this might fail

cd /projects/labs/inventory-wildfly-swarm/ would be safer

OutOfMemory issue on Inventory component

When making requests to the Inventory (wildfly) component, the pod crashes with an out of memory error. The pod will restart but this issue seems to happen constantly. The problem seems that the Max Metaspace size is set to 100m, which is too small in this case.

Solution -
You are required to set the "GC_MAX_METASPACE_SIZE" variable in the Inventory Deployment config
as per this ticket resolution - https://access.redhat.com/solutions/3394951

After manually setting this environment variable to "300" the issue did not appear anymore.

[continuous delivery module] gogs url isn't clickable

Wrong Screenshot Lab 3

Screenshot is wrong under 'Creating a Domain Model'

[debugging applications] path to swarm not full

related to #24 we may wish to use the full path when telling users where to go in the terminal.

[RFE] Curl to G-Form

Should add a curl within the APB to document utilization.

[continuous delivery module] RFE - why don't we precreate gogs account?

Is there a reason the gogs user account isn't precreated like we do for the starter workshop?

[debugging applications] debug connection fails / timeouts if previous pipeline is deploying

the pipeline lab says to test delivery as the last step.

I happened to magically try to debug right as the new pipeline build of the inventory pod was deploying. This resulted in a weird error about the pod not being able to be found.

We may wish to add a warning to the debug lab that they should wait for the test pipeline delivery to finish before continuing.

[wildfly swarm module] che shows errors when loading InventoryApplication.java

When first loading the file, Che shows errors on the various imports. It's not until the Maven build runs that the errors disappear.

• why is this?
• should we include a warning that the errors will go away?

[service resilience module] ocp 3.11 changes delete behavior and "terminating" won't be visible

I noticed this when testing something else. in OCP 3.11 the oc delete behavior is changed. The command doesn't actually seem to return until after the specified pod is already terminated, so you won't see the terminating state any more, even if you use ; or && between the delete and the get.

[continuous delivery module] RFE - jenkins/maven builds should use local nexus repo

It doesn't appear that the pipeline builds are using the internal nexus repo:

Downloaded: https://maven.repository.redhat.com/ga/org/jboss/eap/wildfly-clustering-web-undertow/7.1.1.GA-redhat-2/wildfly-clustering-web-undertow-7.1.1.GA-redhat-2.jar (102 kB at 4.2 kB/s)

[debugging applications] curl of inventory endpoint not in command box

the curl of the inventory endpoint is not in a command box -- it's just block text.

Remove guides-che when removing the APB

[wildfly swarm module] stop icon only appears when on "run wildfly-swarm" tab

The instructions have you use curl to hit the test URL and then say "you can..." with the browser. If the user doesn't use the browser, they will still be on the terminal tab.

When on the terminal tab, the stop icon does not appear when you mouse over the "run wildfly-swarm" machine.

Disable CHE in the Guides using a ENV var.

CHE workspace is very slow and a great resource consumer. We should have an ENV var to disable it

[RFE] bash to make curling deployed inventory easier

Copy/paste out of the Che terminal is kind of a bear. The following bash makes it so that you don't need to copy/paste:

`curl http://`oc get route inventory -o jsonpath --template='{.status.ingress[0].host}'`/api/inventory/329299`

[continuous delivery module] new-app command for jenkins isn't in command box

the jenkins new-app command appears as red block text as opposed to being in a command / copy-paste box.

Lab 6 Dockerfile is missing LABEL

Add

LABEL "com.redhat.apb.spec"=

after FROM

Project Skeletons

Looks like you don't have to "Convert to Project" any more with a newer version of CodeReady.

CHE Requires a user to be registred first.

There's no instruction on the guides that tells attendees to register themselves before using CHE

[service resilience module] siege command does not appear in command block

looks like the asciidoc annotation might have a typo

We should make CHE settings.xml point to NEXUS_URL

In that case we would make NEXUS_URL act as a proxy for every workshop attendee.

[getting started module] "Open in IDE" and not "Open"

Click on Open to open the workspace and then on the Start button to start the workspace for use, if it hasn’t started automatically.

Should this read "Open in IDE" as the button doesn't only say "Open"?

[app config module] deleting catalog pod with label also deletes its pgsql container

oc delete pod -l app=catalog causes the pgsql container/pod to be deleted as well.

oc delete pod -l deploymentconfig=catalog will only delete the catalog pod without deleting the pgsql pod.

Openshift OAuth not working with Cloud Ready workspaces on a 4.1 cluster

When having cloud ready workspaces set up on an OpenShift 4.1 cluster the OpenShift OAuth login with Code Ready Workspaces does not work and provides a "Were Sorry Unexpected error when handling authentication request to identity provider message" The log stream in the codeready workspaces pod is showing a warning message of

"2019-11-13 21:36:55,904[75f-cp6fm-48701] [WARN ] [unknown.jul.logger 49] - Problem getting Pod json from Kubernetes Client[masterUrl=https://172.30.0.1:443/api/v1, headers={}, connectTimeout=5000, readTimeout=30000, operationAttempts=3, operationSleep=1000, streamProvider=org.openshift.ping.common.stream.TokenStreamProvider@dff9cfb] for cluster [EclipseLinkCommandChannel], namespace [lab-infra], labels [app=che]; encountered [java.lang.Exception: 3 attempt(s) with a 1000ms sleep to execute [OpenStream] failed. Last failure was [javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target]]"

But am not sure if it is related to the OAuth authentication attempt though. Please reach me at [email protected] if this is able to be resolved.

[debugging module] lab guide errors do not appear

lab guide says:
