Troubleshooting

Fix Elasticsearch map count error:

When you launch the Docker environment on some Linux systems, the Elasticsearch service fails to start and the following error displays:

1
2
ERROR: [1] bootstrap checks failed
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

To fix the error, run the following sysctl command to increase the memory map area allocation.

1
sysctl -w vm.max_map_count=262144

To permanently update the system setting for vm.max_map_count:

1. Edit the sysctl configuration file (etc/sysctl.conf) and set the required value for the vm.max_map_count option.

2. Reboot your system.

3. Run the following command to verify the change.

   1
   sysctl vm.max_map_count
