devops - ansible different sections, different hosts same playbook -


i have use case need task (reissue ssl certs). steps go this:

  • open port on ca server
  • generate cert on normal server, contacts ca
  • close port on ca server

this means have playbook looks this:

- name: open port   hosts: caserver   become: yes   tasks:     - name: open firewall       iptables: chain=fwr protocol=tcp source={{ item }} destination_port=8888 jump=accept state=present       with_inventory_hostnames: here???  - name: generate ssl certificate   hosts: all:!caserver   become: yes   roles:     - sslcert  - name: close port   hosts: caserver   become: yes   tasks:     - name: close firewall       iptables: chain=fwr protocol=tcp source={{ item }} destination_port=8888 jump=accept state=absent       with_inventory_hostnames: here???

then call command line using limits control machines re-issued.

ansible-playbook -i hosts -l myserver,caserver -c ssh --ask-vault-pass -k generate_certs.yml

the problem not opening port on caserver.

i have been trying of magic variables , no luck.

i thinking have create group in hosts file , use that. i'd make group, re-issue , remove them group.

i'd not shuffle there better way in ansible?

you should use delegation.

- name: generate ssl certificate   hosts: all:!caserver   become: yes    pre_tasks:     - name: open firewall       iptables: chain=fwr protocol=tcp source={{ inventory_hostname }} destination_port=8888 jump=accept state=present       delegate_to: caserver    roles:     - sslcert    tasks:     - name: close firewall       iptables: chain=fwr protocol=tcp source={{ inventory_hostname }} destination_port=8888 jump=accept state=absent       delegate_to: caserver

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
