Basic Ansible connection plug-in mostly useful for testing functionality,
|
|
due to Ansible's use of the multiprocessing package a lot more work is required
|
|
to share the mitogen SSH connection across tasks.
|
|
|
|
Enable it by:
|
|
|
|
$ cat ansible.cfg
|
|
[defaults]
|
|
connection_plugins = plugins/connection
|
|
|
|
$ mkdir -p plugins/connection
|
|
$ cat > plugins/connection/mitogen_conn.py <<-EOF
|
|
from mitogen.ansible.connection import Connection
|
|
EOF
