Elasticsearch fails to start

[tylers-username]

Issue Description

Elasticsearch (maybe just version 7?) fails to start.

Re-create the issue

Create a Lando-compatible PHP project and add the following service:

magento_search:
  type: elasticsearch:7.7
  disk: 256
  configuration:
    plugins:
      - analysis-icu
      - analysis-phonetic

Then, lando start.

lando logs -s magento_search outputs:

magento_search_1  | NameError: 'all_node_ips' is not defined
magento_search_1  | Traceback (most recent call last):
magento_search_1  |   File "/usr/lib/python2.7/dist-packages/platformsh/agent/service.py", line 379, in generate_config_files

magento_search_1  |   File "_etc_elasticsearch_elasticsearch_yml_psh_tmpl", line 23, in render_body

With a partial fix implemented (described below), a refreshed log contains:

magento_search_1  | NameError: 'all_hostnames' is not defined
magento_search_1  | Traceback (most recent call last):
magento_search_1  |   File "/usr/lib/python2.7/dist-packages/platformsh/agent/service.py", line 379, in generate_config_files

Solution

1. lando ssh -s magento_search -c 'nano /etc/elasticsearch/elasticsearch.yml.psh-tmpl'
2. remove the line containing all_node_ips and then remove the line containing all_hostnames
3. lando restart
