In my previous blog posts I have looked at using an Ansible playbook to install the ELK (Elasticsearch, Logstash, Kibana) stack across three different computers, and then how Ansible roles can be used to organise a playbook.…

Continue reading →: Using Ansible Roles, aka ELK Stack Ansible Playbook (V2)I have a working Ansible Playbook that installs the ELK stack (Elasticsearch, Logstash, Kibana and for this example, Filebeat) across three different computers. I have tested the playbook several times and it works each time which is a great sign, however the playbook itself is a little messy. Note: All…

I’m currently spending time learning more about the ELK stack, which is made up of ElasticSearch, Logstash, Kibana (ELK) and Beats. The ELK stack can be created and run within containers (e.g. Docker) but I am going to use an Ansible Playbook to install and configure the ELK stack. You…
