Arranger needs the correct Elasticsearch credentials to access the ES cluster. By default the username and password for Elasticsearch is elastic and myelasticpassword.
However, if these values need to be changed, they can be modified prior to deploying the ES service. To do this you will need to update Arranger's Makefile.
Makefile in an editor and look for the #Variables section:# VariablesDOCKER_DIR := $(ROOT_DIR)/dockerES_DATA_DIR := $(DOCKER_DIR)/elasticsearchES_HOST := http://localhost:9200ES_INDEX := file_centric_1.0ES_LOAD_SCRIPT := $(ES_DATA_DIR)/load-es-data.shES_PASS := myelasticpasswordES_USER := elasticRETRY_CMD := $(ROOT_DIR)/scripts/retry-command.shES_BASIC_AUTH := $(shell printf "$(ES_USER):$(ES_PASS)" | base64)
Modify the ES_USER and ES_PASS to the credentials of your choice.
Run the installation as normal. Our Installation guide can be found here.
