Structure

• ./entry.sh is entry point script for provisioning
• ./PLATFORM is directory of each PLATFORM (ubuntu18, centos7, etc...)
• ./PLATFORM/SCRIPT is script for provisioning (ex. docker.sh, apache.sh, etc...)
• ./PLATFORM/files/SCRIPT is directory of configuration files
  • ex. ./PLATFORM/files/SCRIPT/etc/apache2/conf/httpd.conf is original file of /etc/apache2/conf/httpd.conf.
    • ./PLATFORM/files/SCRIPT is path prefix. This file supposes that will be copied to same path of target server or container.

Usage

Manualy

# <PLATFORM> is platform environment (ex. "amazon2", "ubuntu18" and more)
# <SCRIPT> is provisioning script file name

curl -fLsS https://git.io/prv-bash | bash -s <PLATFORM> <SCRIPT> [SOME ARGS...]
