using vmctl to copy data

-
I had a need to copy data from a standalone victoriametrics system to a cluster setup. for some reason the command line wasn't intuitive, so making a note here 


./vmctl vm-native --vm-native-src-addr=https://source.to.copy.from:443
 --vm-native-src-user user1 --vm-native-src-password password1
 --vm-native-dst-addr=https://destination.to.copy.to:443/insert/0/prometheus/api/v1/write 
 --vm-native-filter-match='{db="db1"}'

using t1n1wall, opnsense or pfsense on Google Compute Engine GCE

-
I have been doing some work in GCP recently, both appengine , and GCE.  We wanted to make sure all our instances were on private ips and only the LBs had internet ips. This gave us the problem of how to allow our instances reach the internet for updates or for api calls outside. In AWS you had a NAT gateway, but in GCP this doesn't exist. So I set about looking at the easiest way to do NAT from a private IP subnet to a Public address.  I am very familiar with m0n0wall and t1n1wall and a tiny bit with pfsense and less with opnsense. The tl;dr is that all these distributions ship an image which within the distribution there is a disk image.  Taking this internal image, renaming it and re-compressing it is all you need to do to get it working in GCE. you can configure it via the serial port using these instructions  There are guides out there around doing things with Linux and stuff, but you can skip that step. I took the latest version ...

nginx decode base64 url for use with imgproxy

-
 i've been testing imgproxy, to handle our image serving needs, and it looks good. our existing servers are php based, and we sign and encode our urls for images.  To test out imgproxy , I wanted to simply drop it in as a replacement for our servers by sending a % of traffic.  There are many ways to do this, varnish was one, with custom code, but nginx is our go-to web server, so I had to find a way to have nginx sit in front of imgproxy and rewrite the decoded url. I settled on using njs, the cut down version of javascript that plugs into nginx as a loadable module.  Then use proxy_pass to pass the uri to javascript that will return the imgproxy compatable url, and proxy to it. a sample url would be http://foo.bar/images/c2lnbmF0dXJlZm9vaHR0cDovL3MzLWV1LXdlc3QtMS5hbWF6b25hd3MuY29tL215YnVja2V0b2ZwaG90b3MvcGhvdG9fb2ZfYV9jYXQ1fHx8MTIwMHgxMjAwfHx8fHx8fHw==.jpeg it has a sig, a bucket url, and parameters like image size. Getting nginx setup nginx.conf load_module modu...
