| 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](http://docs.ansible.com/ansible/latest/user_guide/playbooks_tags.html). |
| |
| 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 }}' } |
| |

| 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 } |
