You can install the ELK tool with the attached docker-compose-elk.yml file.
To install it you should create a new stack and copy the content of the configured elk compose file then Deploy the new stack.
Before compose-up execute the following command on the host machine:
sudo echo “vm.max_map_count=262144” >> /etc/sysctl.d/elasticsearchSpecifications.conf && sudo sysctl –system
You can change the default storage path of the ELK application. For that, you have to configure the left side from the colon that lines which are starting with /srv/docker at volume sections.
