@dustymabe we'll need another cached image for this lab - registry.access.redhat.com/rhscl/mariadb-101-rhel7@sha256:cfbb641b1e1c42dc16d6670ab931914eefe9134cacc2d26504997370b4104e96

it appears as though it may already be cached though...

$ oc get images --as=system:admin | grep -i rhscl\/mariadb

is it there? /me really doesn't want to respin the image at this point.

tchughesiv commented 7 years ago

sure does seem that way... just recreated the minishift env and it appears before i even deploy anything.

trying to find it on the disk now.

looks like there are several already on imported... all done 6 days ago... on the 7th. Is that when you recreated the image?

Best way to test this chapter (really the whole lab) is without network connectivity.

@scollier i've made some changes ... let me know if they solve your functional issues.

As far as formatting of notes, etc, goes... I'm indifferent. Make whatever changes you think would be best.

tchughesiv commented 7 years ago

@dustymabe i'd love to be able to demonstrate the included mariadb template... i think its a big plus for openshift devs... but, worst case... if it would require a rebuild on your part and you didn't want to do that... we can probably modify this chapter to use the mariadb image which is built in ch3.

dustymabe commented 7 years ago

ok, finally got a chance to run through this - my idea for "exploring openshift" was more to take the students on a tour of the web interface. We can do what you've got here in this lab5, but it does seem a bit advanced as we kinda just throw the user into deploymentconfigs and imagestreams without really introducing them.

is there a way we can get more of a "exploring your application in the openshift web console" part of this chapter?

as for embedding the mariadb image into the labvm, i can try to make a new image late tomorrow, but I don't know if scott mcB will take it at this point. Worst case scenario we can just "talk about" the image options and what one "could" do if they wanted to use them.

tchughesiv commented 7 years ago

K, this actually felt less "advanced" to me than the last chapter because they don't necessarily have to understand imagestreams or DC's to use them easily in openshift and they don't have to create a bunch of yaml files. We can explain them in little one-liners though at high level if that makes it better?

Or we scrap it, and stick with the chapter 4 stuff... but that feels more involved to me and doesn't speak to some of the ease of use of our platform.

scollier commented 7 years ago

@tchughesiv @dustymabe if this requires a respin, need to decide today what is going to happen.

tchughesiv commented 7 years ago

sounds like we will have some internet access?... just potentially saturated? another option could be we just kick of a pull off the mariadb image for the students before they started the labs. by the time they got to lab5, it'd be done... would likely be done before they even start any labs.

tchughesiv commented 7 years ago

Ch. 5 mods to-do

tchughesiv commented 7 years ago

moved to template file deployment model as discussed... web console walkthrough is next on my to-do list.

tchughesiv commented 7 years ago

@scollier & @dustymabe should we merge this as is now and have a separate PR for the web console additions? or?

dustymabe commented 7 years ago

Tommy, mostly looks good to me. maybe address a few of langdon's comments and then merge this. We can iterate from there
