Getting started

Usage from TFTP clients

If you try to check if the TFTP server works using a TFTP client, ensure that the client host can receive UDP packets on port 69 (tftp). This port might be blocked by the firewall on the client side.

Conditional write access

If the tftpd__allow variable is defined to limit the access to the TFTP service to specific subnets, the role will automatically enable write access in the tftpd-hpa service. The tftpd__upload_directory defines the name of the directory in the TFTP root directory which will be created by the role to allow file uploads.

Example inventory

To configure a TFTP server on a host, you should add it to the [debops_service_tftpd] Ansible inventory group:

[debops_service_tftpd]
hostname

Example playbook

If you are using this role without DebOps, here's an example Ansible playbook that uses the debops.tftpd role:

---

- name: Manage TFTP service
  hosts: [ 'debops_service_tftpd', 'debops_tftpd' ]
  become: True

  environment: '{{ inventory__environment | d({})
                   | combine(inventory__group_environment | d({}))
                   | combine(inventory__host_environment  | d({})) }}'

  roles:

    - role: debops.ferm
      tags: [ 'role::ferm', 'skip::ferm' ]
      ferm__dependent_rules:
        - '{{ tftpd__ferm__dependent_rules }}'

    - role: debops.tcpwrappers
      tags: [ 'role::tcpwrappers', 'skip::tcpwrappers' ]
      tcpwrappers__dependent_allow:
        - '{{ tftpd__tcpwrappers__dependent_allow }}'

    - role: debops.tftpd
      tags: [ 'role::tftpd', 'skip::tftpd' ]

Ansible tags

You can use Ansible --tags or --skip-tags parameters to limit what tasks are performed during Ansible run. This can be used after a host was first configured to speed up playbook execution, when you are sure that most of the configuration is already in the desired state.

Available role tags:

role::tftpd
Main role tag, should be used in the playbook to execute all of the role tasks as well as role dependencies.
