cli: status command #768

sadjamz · 2021-10-07T08:04:42Z

Based off of a demo branch worked on here: https://github.com/hashicorp/consul-k8s-cli/tree/status

Changes proposed in this PR:

consul-k8s status checks the status of your Helm install and some Kubernetes components like the clients, servers, and webhook deployments.
The checkHelmInstallation() function uses the Helm Go SDK to run a helm status, printing the status of the release, the version, and the config. Config is all of the values overridden from values.yaml. This function also iterates through each of the hooks and prints the phase of each 'pre-install' or 'pre-upgrade' hook.
checkConsulServers() and checkConsulClients() lists the Stateful Sets and Daemon Sets and compares the desired replicas to the ready ones. This determines if all the clients/servers are healthy or not.

How I've tested this PR:
Manual testing, along with writing a few unit tests.

How I expect reviewers to test this PR:

Code review
Test it out:
cd cli
go build -o ./bin/consul-k8s
./bin/consul-k8s status
Run the two unit tests in cli/cmd/status/status_test.go

Checklist:

Tests added
CHANGELOG entry added

HashiCorp engineers only, community PRs should not add a changelog entry.
Entries should use present tense (e.g. Add support for...)

Did a quick code review, will test out the command and give a more thorough review soon! Great work on this so far!!!

About to start looking at the code. I pulled this down and tried to run it but I got this response:

I get this response when running against a cluster that does not have Consul installed.

t-eckert · 2021-10-12T18:30:36Z

About to start looking at the code. I pulled this down and tried to run it but I got this response:

Error returned from consul-k8s status

Note that I only saw this running go 1.17.1. When I downgraded to 1.16.9 the issue went away. 🤷

You are doing great so far, Saad. I added some comments and will re-review later.

Outside of the scope of this PR, some of the content has me thinking that logic could be separated out so that a consul and a helm package exist. I think you'll have a lot of repeated logic across the different commands which might be consolidated using a cleaner architecture.

sadjamz · 2021-10-18T22:45:58Z

I get this response when running against a cluster that does not have Consul installed.

@ishustava and @NicoletaPopoviciu's bug fix while completing the following asana task fixed this issue!

I think this is pretty solid on the whole! Definitely fix the time formatting and make the linter happy, then it's good in my book.

ndhanushkodi

This is coming together great Saad! I think the date/time rendering is the main fix, everything else is small nits!

Edit: I see you got to the date/time rendering before I submitted to the review :)

s := "Usage: consul-k8s status" + "\n" + "Get the status of the current Consul installation." + "\n\n"

Little lost here, why do we need two new-lines? Interestingly enough the help command outputs the same thing either way.

Ah ok, nvm then. I noticed that the Global options displayed right underneath the help text so I thought adding an extra newline would make the output look more consistent with the install command's help message
