...another beautiful day at work!

...but wait - there is an importante-mail in my inbox!

1 The client needs PoC ASAP

2 Next week 1 mln hits campaign!

3 Agency is ready for content entry!

Mainframe

4 Ad-hoc infrastructure!

5 Monitoring/maintenance required!

Mainframe

It seems like huge pressure and a lot of work to do...

...or maybe rather a lot of CQ clicks!

Managing a cloud of...

...thousands of AEM/CQ instances

...hundreds of dev, test, qa, uat, live environments...tens of client deployments

in a consistent way!

Use AEM/CQ REST infinitive possibilities!

UNIXUNIXTry the github.com/Cognifide/CQ-Unix-Toolkit!

Start using it!Help us develop it!

What is the CQ Unix Toolkit?

+ + = UNIXUNIX

open source user-friendly curl wrapper

set of independent simple micro tools

AEM/CQ HTTP REST semi-code/semi-documentation

allows to control CQ/dispatcher by HTTP

Commons are extracted into one cqapi tool.

+ + = UNIXUNIX

Use cases

Case 1 — distributed REST knowledge

No common place for AEM/CQ REST documentation!

Case 2 — hacking packages

1 Installing hotfixes/releases automaticallycqput; cqrun

2 Synchronizing content between instancescqpkg; cqput; cqbld; cqcp; cqrun; cqsnp

3 Making path-based backupscqpkg; cqput; cqbld; cqcp

4 Uninstalling deleted packagescqsnp

5 Clearing content pathscqpkg; cqput; cqrun

6 Moving paths from repository externallycqpkg; cqput; cqrun; cqsnp; cqsnp

7 Deleting unknown/garbage packagescqls; cqdel; cqsnp

Case 3 — monitoring/maintenance

DevelopmentCreate new tools with us!

Organize the AEM/CQ REST World!

Rule 1 — Capture day to day requests

Rule 2 — Write user-friendly usage messages

$ cqbldUsage: cqbld [OPTION...] package-nameBuild (rebuild) already uploaded package by group id and name in CQ PackageManager using instance URL. Examples: cqbld -u admin pack # Build package named pack cqbld -u admin -g GRP pack # Build package named pack in group GRP cqbld -i http://localhost:5510 # Build package for localhost instance on tcp -g com.group stuff # port 5510 named stuff in group:com.group -p secret # with password provided: secret

Options:

-u use specified usernamed for connection -p use provided password for authentication -i use specified instance URL to connect -g locate package by additional group ID

Rule 3 — Choose descriptive code over comments

# Invoke curl tool with current referer and # instance URL and credentials to get list # of packages STATUS=`$CURLBIN -s --write-out "%{http_code}"\ -u "$u:$p" -H "Referer: $url/crx/packmgr"\ -F cmd=ls "$url/crx/packmgr/service.jsp"`

PACKAGE_MANAGER_PATH="/crx/packmgr"REFERER="${instance}${PACKAGE_MANAGER_PATH}" AUTH="${username}:${password}" FILEPATH="${PACKAGE_MANAGER_PATH}/service.jsp" FULL_URL="${instance}${FILEPATH}" REFERER_HEADER= "Referer: ${REFERER}" COMMAND="cmd=ls"

Use shellcheck.net to validate POSIX shell syntax!

STATUS=$("${CURLBIN}" \ -s \ --write-out "%{http_code}" \ -u "${AUTH}" \ -H "${REFERER_HEADER}" \ -F "${COMMAND}" \ "${FULL_URL}")

Rule 4 — Use POSIX getopts for custom parameters

while getopts ":abc${apigetopts}" optdo case "${opt}" in

\?) echo "Invalid option: -${OPTARG}" >&2; _usage;; :) echo "Option -${OPTARG} requires an argument." >&2;

_usage;; esac done

Rule 5 — Use cqapi to detect/handle curl command

shared code, status, parsing common options, error handling

Rule 6 — Use the most usable REST HTTP

choose!

Rule 7 — Reserve API cmdline options for CQ/AEM connectivity

-u username-i instance URL-p password

Rule 8 — Avoid including external custom dependencies

This can be harmful,hard in use and notportable!

Rule 9 — Keep It Simple Stupid

Keep toolkit filesas small as possibleup to 400 LOC

Manage complexity!Simplify logic!
