Before we start, please note the following:
Own backup plan
When you have your own backup mechanism implemented you may skip the backup steps described in this guide.
REST API
We advice you to use a GUI tool like postman to manage REST API calls / HTTP requests.
In the following we give examples with the command-line tool cURL. You don't have to but you can run these on the COYO host.

Don't skip major Versions
If you need to update to a higher version, from v14.x to 21.x, in example, please note that you first update v14 to v18 and then v18 to v21.

Higher System requirements in Version 18+
Due to a new second level cache please expect an additional 25% load on all backend nodes and 4-6GB of additional RAM. Due to higher complexity of the application please expect an additional 25% load on all Elastic Search nodes.
We also prepared a Video guide:
Step-by-step Guide
The update of an existing installation is done in a few simple steps.
We provide enterprise packages here. Just download the new release with wget into your COYO home directory and follow these easy steps:
1. Announce maintenance work some hours early with a maintenance message via REST API's management endpoint. Please set duration (time till message disappears by itself) and message depending on your needs.
(Make sure to replace the COYO_* parameters with the values in your .env file)

#Backup Status prüfen:
curl -u 'COYO_MANAGEMENT_USER':'COYO_MANAGEMENT_PASSWORD' https://COYO_BACKEND_URL:8083/api/backups 4. Stop COYO with the ./stop.sh script
5. Unzip the downloaded release and replace/rename files like this:
root@coyo-host:/home/coyo unzip coyo4_<version>-RELEASE.zip
Archive: coyo4_<version>-RELEASE.zip
replace .env? [y]es, [n]o, [A]ll, [N]one, [r]ename: r
new name: .env_<version>
inflating: .env_<version>
replace coyo-push.properties? [y]es, [n]o, [A]ll, [N]one, [r]ename: n
replace coyo-backup.properties? [y]es, [n]o, [A]ll, [N]one, [r]ename: n
replace stop.sh? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
replace docker-compose.yml? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
replace start.sh? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
replace start-advanced.sh? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
replace coyo-backend.properties? [y]es, [n]o, [A]ll, [N]one, [r]ename: n
replace README.md? [y]es, [n]o, [A]ll, [N]one, [r]ename: y6. Check the new .env file for updates or read our release notes carefully and apply changes to .env file
(When you missed a parameter you'll get a WARN message when running the start.sh script. You should then abort by ctrl + c)
(When you missed a parameter you'll get a WARN message when running the start.sh script. You should then abort by ctrl + c)
These additional parameter in are mandatory and must be existent in your .env file:
in Version 14+
Two new lines are expected. One is for telling the environment to run on only one backend the other one sets the OOM-score to 0 to not kill COYO in case of OOM (out-of-memory).
# Mode for single host installation
COYO_SINGLE_BACKEND=true
# Score for OOM
COYO_BACKEND_OOM_SCORE=0
In Version 21+
You will need to add an authorization key in at least 256 bit. You can use any hash generator online
to generate one.
# Mandatory shared secret used for authorization json web tokens that are used to authorize the user at the services
# (e.g. translation service). Must be at least 256 bit (32 byte) long.
COYO_AUTHORIZATION_KEY=
Attention:
Should you experience ERRORS from the docker-compose.yml file, please make sure that you are on the current supported version of docker-compose (>=v1.26.0.).
7. Start COYO
./start.sh
or start with the optional metrics stack:
./start-advanced.sh
8. Tail the coyo-backend.log till the message "Application started in X seconds" appears and watch for migration errors
tail -f COYO_DATA_STORAGE/backend/logs/coyo-backend.log9. Visit your COYO and deactivate maintenance mode
curl -u 'COYO_MANAGEMENT_USER':'COYO_MANAGEMENT_PASSWORD' \
-X DELETE \
