can sysctl.present have multiple items?

[Yong Zhang]

Hi,

I want to use state sysctl.present to config some sysctl settings, is it possible to define multiple items like below (I tested with below state but doesn't work, just want to know how to define multiple items within one sysctl.present)?

sysctlsettings:

  sysctl.present:

    - name: net.ipv4.tcp_tw_reuse

      value: 1

    - name: net.ipv4.ip_local_port_range

      value: 10240    65535

    - name: kernel.sysrq

      value: 1

    - name: net.ipv6.conf.all.disable_ipv6

      value: 1

    - name: net.ipv6.conf.default.disable_ipv6

      value: 1

    - name: net.core.somaxconn

      value: 262144

No, it is not possible doing exactly what you showed.

The code here says that you can set only 1 item with each sysctl.present https://github.com/saltstack/salt/blob/develop/salt/states/sysctl.py#L30

But you can get the same effect by using a Jinja2 loop over all item, so, create different states

This is an example of doing so  https://github.com/hvnsweeting/states/blob/master/sysctl/init.sls

actually you can. although getting that many different values together kind of looks ugly to me.

sysctlsettings_true:

  sysctl.present:

    - value: 1

    - names:

      - net.ipv4.tcp_tw_reuse

      - kernel.sysreq

      - net.ipv6.conf.all.disable_ipv6

      - net.ipv6.conf.default.disable_ipv6

      - net.ipv4.ip_local_port_range

        - value: 10240 65535

      - net.core.somaxconn

        - value: 262144

Need some colons after somaxconn, and the other ones that have an extra value, but this is how I would do it.
