Docker really isn’t all that easy. If you want all defaults, it’s dandy. If you want customize anything (e.g. save log files or configure it), then it’s not. Grafana has some sort of strange user/permission thing going on. Sorted. The pretty picture is the Stack OS metrics dashboard (gathered by node_exporter, collected by Prometheus, andContinue reading “Grafana Up”

Prometheus Up, Again
Prometheus was mostly working on the ops machine. I tried to Docker it. Prometheus, itself, came up, but none of the cluster.test names resolved. Getting github working proved its worth: git push on the ops machine, then git pull on another, and voila! all the files I need are there. Docker actually proved worthwhile here,Continue reading “Prometheus Up, Again”
On github
No, you cannot see it, yet – it’s not done. I got it rearranged, unified and up there – and made git work on all the VMs, so I can edit from anywhere.
Pulsar Up, Again
While baking cookies, I rewrote the broker scripts for the DNS changes. On the bright side, I never updated them to cluster.dev, so it was straight from IPs to cluster.test. I was confused about why the Bookies had port 6650 mapped when it could not be configured. Turns out, that is a Broker port thatContinue reading “Pulsar Up, Again”
Learning 2 Bake – from Scratch XIX
Another cookie exchange on Friday, so more cookies. At The Laird’s request, pecan. That’s a bit vague, but this Betty Crocker recipe looked good: Butter Pecan Pudding Cookies 2 1/2 cups all-purpose flour1 1/2 teaspoons baking soda1/2 teaspoon salt1 cup butter, softened1 cup packed brown sugar1/2 cup granulated sugar1 box (3.4 oz) Jell-O™ French vanilla-flavorContinue reading “Learning 2 Bake – from Scratch XIX”
Up, Again
And cluster.test is up and running as far as BookKeeper. All six http:// URLs work. All scripts and documents now use cluster.test instead of cluster.dev. (Google is evil!) There were a few bobbles along the way, but I’m getting reasonably good at this, unfortunately. Discovery: When you send –restart always to a docker run command,Continue reading “Up, Again”
Google Is EVIL
I cannot connect a web browser to my new entirely internal domain because I named it cluster.dev and Google has registered “.dev” and hard-coded into browsers that it must be secure. I’m not screwing with TLS infrastructure. Now I need to rename the whole thing. “.test” is supposed to be reserved. We’ll see. Many thanksContinue reading “Google Is EVIL”
Mayonnaise
I wanted a break at lunch, I don’t like roast beef sandwiches with butter, and I had no mayonnaise. Make some! It’s very simple with two “tricks”: Room temperature eggs and very slow drizzle to add the oil. Mayonnaise 2 egg yolks – room temperature is important1 Tbl vinegar (I combine white, red, and lemonContinue reading “Mayonnaise”
ZooKeeper Up – Again
It’s running on names, now. I’ve also restructured the files with the intent to upload it all to github as one package and documented a step-by-step guide, getting this far, at least. Note that I didn’t lose the Zoo data. It’s also generating log files, now, so they can be picked up by logstash (someday)Continue reading “ZooKeeper Up – Again”
DNS Up
BIND doesn’t seem to have a logo, so I picked this. On the off chance anyone sees it, I picked a watermarked picture in the hopes of not running into copyright issues. Aside from the clever name, it’s an interesting site. My virtual machines now have names (and static IPs) and can see each otherContinue reading “DNS Up”
