ansible-server's Introduction

ansible-humio

Installer for Humio. Current features

Launch one Humio instance per CPU socket

Requirements

A running Zookeeper and Kafka installation.

Role Variables

humio_host_id: 0
humio_public_url: "http://{{ ansible_default_ipv4.address }}"
humio_socket_bind: "0.0.0.0"
humio_http_bind: "{{ ansible_eth0.ipv4.address }}"
humio_config:
  all: |
    AUTHENTICATION_METHOD=byproxy
    AUTH_BY_PROXY_HEADER_NAME=name-of-http-header
  "0": |
    HUMIO_HTTP_BIND={{ ansible_eth0_0.ipv4.address }}
  "1": |
    HUMIO_HTTP_BIND={{ ansible_eth0_1.ipv4.address }}
zookeeper_hosts:
  - ip: "{{ ansible_default_ipv4.address }}"
kafka_hosts:
  - ip: "{{ ansible_default_ipv4.address }}"

humio_total_memory_mb can be used to override the memory used by Humio. This defaults to using all memory available on the machine. The JVM memory settings will be determined automatically based on that number using our recommended formula. If you want more fine-grained control, you can set the JVM memory options individually. See the defaults/main.yml file for which variables to override.

Dependencies

Java must be installed. We recommend humio.java galaxy role.

Example Playbook

Ro run a singlenode Humio instance

- hosts: humios
  become: true
  roles:
    - role: humio.java
    - role: AnsibleShipyard.ansible-zookeeper
    - role: humio.kafka
    - role: humio.server

ansible-server's Issues

Invalid data path applied when no secondary storage configured

When no humio_data_secondary_path is configured, the server_n.conf file will collapse DIRECTORYandHUMIO_AUDITLOG_DIR` into a single parameter, i.e.

DIRECTORY=/var/humio/primary/1-0/dataHUMIO_AUDITLOG_DIR=/var/log/humio/0

This causes Humio not being able to start up because path is not writable

Add license file

README.md states license is "Apache", no license file found in repository and repo isn't labled.

Switch to using the Humio tar file and launcher script

I just merged a PR to master that publishes Humio as a tarball very similar to the Kafka distribution.

Once this goes out, I think we should update the Ansible scripts to install this tarball instead of the current fat jar.

Check current Humio version and skip download

Don't download the Humio jar again if the version matches the requested version.

Minor: Humio may not be started at the end of the playbook

Saw a customer use the playbook for stopping Humio. They then ran the playbook to upgrade/deploy Humio. As no files changed, the service was not restarted.

I think we should check if Humio is running, and start it if not.

Overriding autodetected NUMA node count.

A user ran into the case that humio_processes was autodetected to 16, which is too many for their host to handle.

Overriding that value is easy enough, but the underlying numanodes fact is also used for setting environment variables.

https://github.com/humio/ansible-server/search?q=numanodes

Maybe it would be easier for users to control if we had a variable in defaults/main for the ansible_local.numanodes array, so users could replace that as well?

Move humio_public_url

Currently the public_url is being defined in the server specific configuration, this should be in the server_all.conf instead. Setting the public url to the local ipv4 address should only be done in a single node deployment.
