Ansible Playbook error:

TASK [okapi-tenant-deploy : Post install list for deployment and enabling] ********************************************************************************************************************************************************************
fatal: [XXX.XXX.XXX.XXX]: FAILED! => {"changed": false, "connection": "close", "content": "Deployment failed for service mod-search-1.3.0.

s/bvb/install?deploy=true&tenantParameters=loadReference%3Dtrue%2CloadSample%3Dtrue", "vary": "origin"}

Looking at the okapi log, i see:

2021-05-21T20:27:08,505 INFO  DockerModuleHandle   mod-search-1.3.0 20:27:08.500 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
2021-05-21T20:27:08,505 INFO  DockerModuleHandle   mod-search-1.3.0 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'folioEnvironment' defined in file [/opt/folio/BOOT-INF/classes/org/folio/search/con
figuration/properties/FolioEnvironment.class]: Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'okapi.url' in value "${okapi.url}"

So mod-search cannot run. With docker inspect i can see the environment:

           "Env": [
               "DB_MAXPOOLSIZE=5",
               "DB_CHARSET=UTF-8",
               "DB_PORT=5432",
               "ELASTICSEARCH_USERNAME=elastic",
               "SYSTEM_USER_PASSWORD=Mod-search-1-0-0",
               "DB_HOST=192.168.128.89",
               "DB_QUERYTIMEOUT=60000",
               "KAFKA_PORT=9092",
               "ELASTICSEARCH_PASSWORD=s3cret",
               "INITIAL_LANGUAGES=eng",
               "KAFKA_HOST=192.168.128.89",
               "ELASTICSEARCH_HOST=192.168.128.89",
               "DB_USERNAME=folio_admin",
               "ELASTICSEARCH_URL=http://elasticsearch:9200",
               "JAVA_OPTIONS=-XX:MaxRAMPercentage=66.0",
               "ELASTICSEARCH_PORT=9301",
               "DB_DATABASE=okapi_modules",
               "DB_PASSWORD=folio_admin",
               "PATH=/opt/java/openjdk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",
               "LANG=en_US.UTF-8",
               "LANGUAGE=en_US:en",
               "LC_ALL=en_US.UTF-8",
               "JAVA_VERSION=jdk-11.0.10+9",
               "JAVA_HOME=/opt/java/openjdk",
               "JAVA_APP_DIR=/opt/folio"

which is missing the OKAPI_URL Environment.

Meanwhile checking the Ansible Output, i see:

TASK [okapi-tenant-deploy : Build install list for modules with deployment] *******************************************************************************************************************************************************************

....

ok: [138.246.234.10] => (item={'name': 'mod-search', 'version': '1.3.0', 'deploy': True, 'docker_env': [{'name': 'ELASTICSEARCH_URL', 'value': 'http://192.168.128.89:9301'}, {'name': 'OKAPI_URL', 'value': 'http://192.168.128.89:9130'}, {'n
ame': 'JAVA_OPTIONS', 'value': '-XX:MaxRAMPercentage=66.0'}]})  

Where OKAPI_URL and ELASTICSEARCH_URL are correctly set. The same happens to other modules with special environment like mod-pubsub.

I did not yet find the point where the environment gets lost.

Happens on folio-ansible main and r1-2021-release, does not happen on q3-2020-release
 i think.
