Neil, thanks for inspiring ideas.
Currently I have bundles like this
body common control {
bundlesequence => {
"install_packages",
"configure_services",
"check_services",
};
}
bundle agent install_packages {
methods:
configure_ssh::
"install_sshd"
usebundle => verify_package("sshd"),
action => if_elapsed("240");
# etc.
}
bundle agent configure_services {
methods:
configure_ssh::
"configure_sshd"
usebundle => configure_sshd,
action => if_elapsed("240");
# etc.
}
bundle agent check_services {
methods:
configure_ssh::
"check_sshd"
usebundle => verify_service("sshd"),
action => if_elapsed("240");
# etc.
}
and each of these three bundles contains service related promises. I thought
that this could be made more manageable by timing classes.
However now I think that I will have structure like this
body common control {
bundlesequence => {
"configure_services",
};
}
bundle agent configure_services {
methods:
configure_ssh::
"sshd"
usebundle => service_sshd,
action => if_elapsed("240");
# etc.
}
bundle agent service_sshd {
methods:
any::
"install_sshd"
usebundle => verify_package("sshd");
"configure_sshd"
usebundle => configure_sshd;
"check_sshd"
usebundle => verify_service("sshd");
}
Maybe there are some drawbacks compared to my previous implementation. For
example if some bundles need a same package to be installed, the new
implementation will check the package many times. But I think that package
promises are quite efficient?
