Lagoon Core
I'm not sure what the ANSI art is trying to be. If I can get a source image, I'll try to create a clearer one. Upon requesting http://api.lagoon-dev.cms.va.gov/ (HTTPS doesn't work, because reasons), I get:
Which is actually success (at this point)! That means that the routing and ingress are working properly. Next I'll fight with Keycloak, I guess.
I think that's fixable by overriding the keycloakAPIURL in the values file. - name: KEYCLOAK_API
{{- if .Values.keycloakAPIURL }}
value: {{ .Values.keycloakAPIURL | quote }}
{{- else }}
value: https://{{ index .Values.keycloak.ingress.hosts 0 "host" }}/auth
{{- end }}And it works:
Well, sorta:
Probably because this:
So let's override this other URL: - name: GRAPHQL_API
{{- if .Values.lagoonAPIURL }}
value: {{ .Values.lagoonAPIURL | quote }}
{{- else }}
value: https://{{ index .Values.api.ingress.hosts 0 "host" }}/graphql
{{- end }}And:

HarborHarbor... just... kinda worked, I guess. I updated Lagoon-Core with the Harbor admin password, but obv didn't update the Gist.
Lagoon RemoteI created a values.yaml file for Lagoon Remote and deployed the helm chart. It, uh, appears to have deployed successfully:

SSH and SOCKS5I thought Lagoon-CLI used the Go SSH client library, but upon closer inspection it seemed to use the SSH CLI. Then, upon still closer inspection, it only seemed to use the SSH CLI under certain circumstances. After discussing this with Elijah, Eric, and Cameron, we figured that a good course of action would be to modify the Lagoon CLI to support SOCKS5 or ProxyJump/ProxyCommand or something. Elijah opened an issue. This morning, I did some tentative work in that direction. Then I started getting itchy and changed the SSH generated command for the codepath that I was fairly sure was never executed, and -- it started working 😕 diff --git a/pkg/lagoon/ssh/main.go b/pkg/lagoon/ssh/main.go

After some poking around, I think that the answer was just to change my SSH connection info for Lagoon: current: lagoon-dev

GraphiQL doesn't expose any sort of SOCKS proxy configuration.
Fortunately, this is precisely the sort of suffering I've come to expect in engineering.

github.com[0: 192.30.255.112]: errno=Operation timed outHmm. So it looks kinda like there's an outgoing networking issue. When consulted, Eric and Elijah nodded sadly and explained that outgoing requests to port SSH are dropped by the TIC. And although GitHub can be SSH'ed to on port 443 this violates the spirit of TIC law and would get me yelled at. Two solutions are:
A decision on the latter probably isn't possible until Monday, so I'm kinda blocked here. I think I'll go back and see if I can get HTTPS cloning to work. IDK why it wouldn't, but it didn't before. EDIT: Yeah, no, definitely still doesn't work. |

I'm blocked on moving much forward by the outgoing Git/SSH issue, but I can move forward with other things... EFSI created an EFS filesystem This created a storage class with the name That does nothing to unblock me with regard to Git/SSH, though, and I still need to figure out a couple things:

The ops team, in office hours, confirmed our suspicions that this restriction on outbound SSH is pretty legit. As such, this PoC is blocked. We have a number of options for moving forward (h/t Cameron for typing them up):

Roundabout Approaches
A few of the options above could actually be addressed. I've addressed them, sorta, and will discuss. Modifying the Lagoon Build Deploy ImageNo one has responded yet to my discussion thread about git cloning via HTTPS. However, even if they had, it wouldn't work because the DHS is MITMing the TLS. I forked the Lagoon service images, rebuilt the The second half of that was to actually alter the Lagoon configuration to use the new Docker image. I injected the override into the remote-values.yaml and updated the Modifying the codebaseThere are some changes that need to be made to the CMS codebase as part of a move to Lagoon. I made them in #6867, although I have no way of testing them. |

Per this exchange:
There is no way to move forward with this PoC. |

So got some responses on this discussion thread saying that although the build-deploy pipeline was implemented with Git/SSH in mind, that was mostly to accommodate GitHub deploy keys and that there was no real hard reason that HTTPS cloning should not work. Who's to blame?
I mentioned that I'd injected the TIC TLS cert into a Docker container, at which point Toby pointed out that I was using an older Dockerfile -- a great catch which undoubtedly would save me some frustration. So going back to Docker to build the new image: I ran into this issue which seems to plague Docker for Mac. I don't want to upgrade Docker for Mac because that's caused issues with Lando in the past. Fortunately, I have about sixty LXC containers with Docker installed, so I'll just SSH into one of them and build the image and push it from there. Well, then SSH is hanging. I can't SSH into any of said containers, or anything else on my network. SSH works with everything else on my network... except my work computer.
I attempted to find a solution for a few minutes, but being pressed for time I ended up just switching computers, SSHing into my work computer from my personal computer, grabbing the updated Dockerfile, then SSHing into an LXC container to build the The CMS project's URL is HTTPS, so I can attempt to deploy the branch PR to see where my PR (see #6867 ) fails: 🔔nathan.douglas@Belmore:~/Projects/lagoon-stuff$ lagoon deploy branch -p lagoon-dev -b VACMS-6674-lagoon
✔ Yes
successNow I can log into Lagoon UI because Keycloak is running because it's no longer in And:
🎉 It's taking longer to fail than it has before. Which is, technically, progress. So something is requesting Harbor, but doing so via HTTPS and not HTTP. Since I've not specified HTTPS anywhere, this would appear to be an issue with a script somewhere. After doing so, I don't see any commands issued after Why? Well, Docker requires some additional configuration for insecure registries -- configuration that I don't believe the The problem is that I think since this is built around Docker-in-Docker that we're using insecure registries as specified by the host, not by the container. So I think this might be doomed to fail. <snip: I tried it anyway. It failed.> So the only way to move forward at this point, AFAICT, is to add the insecure registry for Harbor to the So I'm blocked again. |

As a CMS engineer, I would like to validate that Lagoon will be sufficient for our needs so that we can begin to evaluate the value and cost-savings that Lagoon potentially offers.
