A regex cheatsheet 👩🏻‍💻 (by Catherine)

let regex;
/* matching a specific string */
regex = /hello/; // looks for the string between the forward slashes (case-sensitive)... matches "hello", "hello123", "123hello123", "123hello"; doesn't match for "hell0", "Hello"
regex = /hello/i; // looks for the string between the forward slashes (case-insensitive)... matches "hello", "HelLo", "123HelLO"
regex = /hello/g; // looks for multiple occurrences of string between the forward slashes...
/* wildcards */
regex = /h.llo/; // the "." matches any one character other than a new line character... matches "hello", "hallo" but not "h\nllo"
regex = /h.*llo/; // the "*" matches any character(s) zero or more times... matches "hello", "heeeeeello", "hllo", "hwarwareallo"

alexanderadam / Ansible Disk Check
Created Sep 15, 2018 — forked from mahemoff/Ansible Disk Check
Show disk space and warn about disk full in Ansible
View Ansible Disk Check
* Shows a message while asserting like:
ok: [host] => {
"msg": "disk usage 4.2B of total 20.0GB (21.0%) (should exceed limit 90.0%)"
}
* Note this only looks at first mount point on current node
* Fails if disk is near-full
* Last step pushes to a push-based monitoring service, which will alert us if it doesn't get there after some time
* Need to setup a variable `disk_limit`, which is the max acceptable usage ratio, e.g. set it to 0.8 if you want to keep disks within 80% of max size

Example Kubernetes pod for the multi-container sidecar design pattern
View pod.yaml
# Example YAML configuration for the sidecar pattern.
# It defines a main application container which writes
# the current date to a log file every five seconds.
# The sidecar container is nginx serving that log file.
# (In practice, your sidecar is likely to be a log collection
# container that uploads to external storage.)
# To run:

REX-Ray with Minio
View README.md

Getting Started

The following command will install the latest version of REX-Ray to /usr/bin/rexray on Linux systems:

$ sudo apt install s3fs
$ curl -sSL https://dl.bintray.com/emccode/rexray/install | sh

Depending on the Linux distribution REX-Ray will be registered as either a SystemD or SystemV service.

Configure

REX-Ray requires a configuration file for storing details used to communicate with storage providers. This can include authentication credentials and driver specific configuration options. After REX-Ray has been installed, copy and paste the contents below to a new file on the host at /etc/rexray/config.yml to configure s3fs storage driver.
