Hi,

I have been trying the following:

tasks:

- name: Disabling IPV6  
lineinfile: dest=/etc/sysctl.conf regexp=${item.regexp} line=${item.line}  
with\_items:
- {regexp=^net.ipv6.conf.all.disable\_ipv6 line=“net.ipv6.conf.all.disable\_ipv6 = 1”}
- {regexp=^net.ipv6.conf.default.disable\_ipv6 line=“net.ipv6.conf.default.disable\_ipv6 = 1”}
- {regexp=^net.ipv6.conf.lo.disable\_ipv6 line=“net.ipv6.conf.lo.disable\_ipv6 = 1”}

But the lineinfile module treats my variables as actual regex string and adds literal “${item.line}” string in my destination file.

How do I put the variable references for lineinfile module regexp and line parameters so that the values are substituted?

It looks like you do not have your YAML hash defined well, it should look like this:

{ regexp: “some value”, line: “some other value” }
