Ansible-based configuration for Linux kernel builders.
Some necessary files/directories are missing from this repository since they contain secrets. In order to make the ansible commands work, those files are necessary and need to be linked in the repository.
The host names in the hosts file are define and used only internally
for the ansible configurations. The real host names and/or their IP addresses
are stored in either the group_vars/ or host_vars/ directory.
To just go through all the tasks, useful to setup a new builder:
ansible-playbook -i hosts site.yml
This assumes that you have configured the host_vars/ and group_vars/
directories with all the necessary parameters from the builder-config-data repository.
If you need to run only a subset of all the tasks, you can limit the ones to run using the available tags:
ansible-playbook -i hosts site.yml --tags=$TAG,$TAG
For example:
ansible-playbook -i hosts site.yml --tags=mips,mirror
If you want to run the tasks only on a subset of the builders, you can limit which one ansible will access:
ansible-playbook -i hosts site.yml -l $HOST_NAME
For example:
ansible-playbook -i hosts site.yml -l kbuilder6,kbuilder7
To check the facts on a host:
ansible -m setup -i hosts $HOST_GROUP_NAME
If you need to run a simple one-time command on the managed hosts:
ansible -i hosts -m raw -a "$SHELL_COMMAND" $HOST_GROUP_NAME
For example:
ansible -i hosts -m raw -a "rm -rf /srv/mirrors" linaro
ansible -i hosts -m raw -a "rm -rf /srv/mirrors" linaro -l kbuilder6,kbuilder7
The latter is limited to kbuilder6 and kbuilder7 only.
Other examples:
ansible -i hosts -m apt -a "name=$PACKAGE_NAME" linaro # Installs a single package across all "linaro" hosts
The -m switch enables to use a single ansible module from all the
available ones.
- The
$HOST_GROUP_NAMEname is the name given, between square brackets, in the hosts file to a group of hosts (i.e.[linaro]).
