ansible lineinfile for several lines

Question

The same way there is a module lineinfile to add one line in a file  is there a way to add several lines   I do not want to use a template because you have to provide the whole file  I just want to add something to an existing file without necessarily knowing what the file already contains so a template is not an option

To add multiple lines you can use lineinfile module with with items also including variable vars here to make it simple      --- - hosts  localhost   change Host group as par inventory   gather facts  no   become  yes   vars      test server   10 168 1 1      test server name   test-server      file dest    etc test test agentd conf     - name  configuring test conf     lineinfile        dest      item dest           regexp      item regexp           line      item line         with items        -   dest       file dest       regexp   Server    line   Server    test server             -   dest       file dest       regexp   ServerActive    line   ServerActive    test server             -   dest       file dest       regexp   Hostname    line   Hostname    test server name

To add multiple Lines in a configuration file you can use  quot   quot  instead of     and escape sequence  n for the new line in lineinfile ansible module  - name  Configure core-site xml   lineinfile      path   etc hadoop core-site xml     insertafter     lt configuration gt       line   quot Line 1  n Line 2  n Line 3 quot

If you need to configure a set of unique property value lines  I recommend a more concise loop  For example   - name  Configure kernel parameters   lineinfile      dest   etc sysctl conf     regexp       item property   regex escape            line      item property       item value       with items      -   property   kernel shmall   value   2097152        -   property   kernel shmmax   value   134217728        -   property   fs file-max   value   65536      Using a dict as suggested by Alix Axel and adding automatic removing of matching commented out entries   - name  Configure IPV4 Forwarding   lineinfile      path   etc sysctl conf     regexp           item key   regex escape            line      item key       item value       with dict       net ipv4 ip forward   1

You can use a loop to do it  Here s an example using a with items loop   - name  Set some kernel parameters    lineinfile         dest   etc sysctl conf        regexp      item regexp            line      item line        with items         -   regexp    kernel shmall   line   kernel shmall   2097152           -   regexp    kernel shmmax   line   kernel shmmax   134217728           -   regexp    fs file-max   line   fs file-max   65536

I was able to do that by using  n in the line parameter   It is specially useful if the file can be validated  and adding a single line generates an invalid file   In my case  I was adding AuthorizedKeysCommand and AuthorizedKeysCommandUser to sshd config  with the following command   - lineinfile  dest  etc ssh sshd config line  AuthorizedKeysCommand  etc ssh ldap-keys nAuthorizedKeysCommandUser nobody  validate   usr sbin sshd -T -f  s    Adding only one of the options generates a file that fails validation

It s not ideal  but you re allowed multiple calls to lineinfile  Using that with insert after  you can get the result you want   - name  Set first line at EOF  1 3    lineinfile  dest  path to file regexp   string 1  line  string 1  - name  Set second line after first  2 3    lineinfile  dest  path to file regexp   string 2  line  string 2  insertafter   string 1  - name  Set third line after second  3 3    lineinfile  dest  path to file regexp   string 3  line  string 3  insertafter   string 2

Here is a noise-free version of the solution which is to use with items   - name  add lines   lineinfile       dest  fruits txt     line      item       with items      -  Orange      -  Apple      -  Banana     For each item  if the item exists in fruits txt no action is taken    If the item does not exist it will be appended to the end of the file   Easy-peasy

To add multiple lines you can use  blockfile   - name  Add mappings to  etc hosts   blockinfile      path   etc hosts     block           10 10 10 10  server example com         10 10 10 11  server1 example com    to Add one line you can use lininfile   - name  server example com in  etc hosts   lineinfile      path   etc hosts     line   192 0 2 42 server example com server      state  present

You can try using blockinfile instead  You can do something like - blockinfile        dest  etc network interfaces backup yes     content  quot iface eth0 inet static         address 192 168 0 1         netmask 255 255 255 0 quot
