# The following changes proved to be necessary to make it work on CentOS 7:
#  * removed disk info (model, size) - not very useful, might not work in many cases.
#  * using "bw" instead of "bw_bytes" to support fio version 3.1 (those availible through yum @base)
#  * escaping exclamation mark in sed command
#  * the ".fiomark.txt" is not auto-removed

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

For a small number of variables ('tokens'), I use a simple shell script along with a templated version of my YAML file. Here's an actual example:

files:

docker-compose-template.yml
docker-compose.yml
compose_replace.sh

run:

#     FreeBSD 9.1 ZFS Health Check script 
#     zfs_health.sh @ Version 0.15

# Check health of ZFS volumes and drives. On any faults send email. In FreeBSD
# 10 there is supposed to be a ZFSd daemon to monitor the health of the ZFS
# pools. For now, in FreeBSD 9, we will make our own checks and run this script
