Apigee OPDK Setup OS Sysctl

This role performs updates to sysctl.conf.

Requirements

None

ipv6 Tag

Please note that IPV6 is disabled in this role. If you need to by-pass this functionality because IPV6 is already being disabled on a system then you can accomplish this by invoking the playbook with the --skip-tags flag like this:

ansible-playbook install-edge.yml --skip-tags=ipv6 

Additional information regarding how Ansible uses tags can be obtained here.

Role Variables

The collection sysctl_ipv6 are the attributes that should be updated in order to disable IPV6 on a node. IPV6 must be disabled on all nodes that are part of an Apigee platform instance.

sysctl_ipv6:
- { name: 'net.ipv6.conf.all.disable_ipv6', value: '1' }
- { name: 'net.ipv6.conf.default.disable_ipv6', value: '1' }

The collection sysctl_minimum are the attributes that should be updated on all nodes that are part of an Apigee platform instance:

sysctl_minimum:
- { name: 'vm.swappiness', value: "{{ vm_swappiness }}" }
- { name: 'net.ipv6.conf.all.disable_ipv6', value: '1' }
- { name: 'net.ipv6.conf.default.disable_ipv6', value: '1' }
- { name: 'net.ipv4.tcp_fin_timeout', value: "{{ apigee_net_ipv4_tcp_fin_timeout }}" }
- { name: 'vm.max_map_count', value: '{{ apigee_max_map_count }}' }

Dependencies

None

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  roles:
     - { role: apigee-opdk-setup-os-sysctl }
