Problem in initializing the indexes on Elasticsearch

[shivaabed1994]

Hi, I have worked on launching this search engine, but I have some questions. First: When the last command (docker exec nexvisions-torscraper-onion-crawler /opt/torscraper/scripts/elasticsearch_migrate.sh) run I got this error: Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/urllib3/connection.py", line 169, in _new_conn conn = connection.create_connection( File "/usr/local/lib/python3.8/site-packages/urllib3/util/connection.py", line 73, in create_connection for res in socket.getaddrinfo(host, port, family, socket.SOCK_STREAM): File "/usr/local/lib/python3.8/socket.py", line 918, in getaddrinfo for res in _socket.getaddrinfo(host, port, family, type, proto, flags): socket.gaierror: [Errno -3] Temporary failure in name resolution

During handling of the above exception, another exception occurred:

What can I do to resolve this error?

Hi, @shivaabed1994, it looks like the elasticsearch container is not up in your environment. Can you check its status and share the log of elasticsearch instances?

[shivaabed1994]

Hi @NexvisionLab Yes I checked those elasticsearch logs and fix the problem. The problem occurred because of volume commands in Docker file.
