5. What is ANSIBLE
6. Fictional machine Comunication Anywhere Fast http://en.wikipedia.org/wiki/Ansible
7. Fictional machine Comunication Anywhere Fast http://en.wikipedia.org/wiki/Ansible
8. ORCHESTRATION engine
9. ORCHESTRATION engine
10. PROPERTIES
11. Python 2012 Fast growth “*nix”
12. Puppet Chef Ansible SaltStack YML YML RB PP
13. WHY should I USE IT?
14. Less errors Fast DRY KISS
15. WHERE should I USE IT?
16. Servers Dev boxes Common computers
17. Servers Dev boxes Common computers EVERYWHERE
18. Ansible KEYS
19. Repo (Chef server) Prod servers (Chef nodes) Devops (Chef Knife) Pull mode Test servers (Chef nodes)
20. Repo (Chef server) Prod servers (Chef nodes) Devops (Chef Knife) Pull mode Test servers (Chef nodes) TOO COMPLICATED
21. Prod servers Devops (Ansible manager) Push mode Test servers SSH SSH
22. Prod servers Devops (Ansible manager) Push mode Test servers SSH SSH TOO SIMPLE
23. KEEP CALM AND USE YAML
24. Hosts 192.168.100.40 192.168.100.41 192.168.100.42 192.168.100.43 hosts http://docs.ansible.com/intro_inventory.html#hosts-and-groups

48. 1st example ANSIBLE CMD
49. 1st example ANSIBLE CMD Wow Such Ansible Much example Excitement Very concentrated im hakerz So devops
50. https://github.com/slok/devops-course/tree/master/02 Lets DOGE our MOTD
51. Hide system info file: /usr/share/landscape/landscape-sysinfo.wrapper mode: rw-r-r Copy message data src: files/doge.txt dest: /home/vagrant/doge.txt Create the new motd src: files/30-doge dest: /etc/update-motd.d/30-doge mode: rx-r-r Update motd cmd: run-parts /etc/update-motd.d/
52. Ansible PLAYBOOKS
53. Real power Multiple tasks Made of actions http://docs.ansible.com/playbooks.html Conditionals, loops...
54. Ansible-playbook PLAY [all] ******************************************************************** GATHERING FACTS *************************************************************** ok: [doge0.dogebox.org] TASK: [Deactivate ubuntu information] ***************************************** ok: [doge0.dogebox.org] TASK: [Copy the resource] ***************************************************** ok: [doge0.dogebox.org] TASK: [Create the new motd] *************************************************** ok: [doge0.dogebox.org] PLAY RECAP ******************************************************************** doge0.dogebox.org : ok=4 changed=0 unreachable=0 failed=0 $ ansible-playbook ./main.yml -i./hosts -l doge0* use -l to limit the target Run your playbooks with ansible-playbook cmd
55. Structure - hosts: devserver tasks: - name: Update repos apt: update_cache=yes main.yml devserver.example.org ansible_ssh_host=192.168.100.40 prod.example.org ansible_ssh_host=192.168.100.41 [devserver] devserver.example.org [web] prod.example.org hosts Minimun files are hosts and playbook starting file
56. Tasks - hosts: devserver tasks: - name: Update repos apt: update_cache=yes - name: Install python apt: pkg: python state: present update_cache: yes main.yml The tasks are the unit actions for Ansible
57. Variables - hosts: devserver vars: # settings for ansible to connect to the vagrant machine ansible_ssh_user: "vagrant" ansible_ssh_private_key_file: ~/.vagrant.d/insecure_private_key docker_user: vagrant remote_user: vagrant sudo: true main.yml Variables can be used everywhere
58. Assign variables - name: test play hosts: all tasks: - name: Cat motd shell: cat /etc/motd register: motd_contents main.yml Use register to assign the task output to the variable
59. Facts doge0.dogebox.org | success >> { "ansible_facts": { "ansible_all_ipv4_addresses": [ "10.0.2.15", "192.168.100.40" ], "ansible_all_ipv6_addresses": [ "fe80::a00:27ff:fe2e:7e37", "fe80::a00:27ff:fe61:c9a1" ], "ansible_architecture": "x86_64", "ansible_bios_date": "12/01/2006", "ansible_bios_version": "VirtualBox", ... "ansible_distribution": "Ubuntu", "ansible_distribution_release": "trusty", "ansible_distribution_version": "14.04", ... "changed": false } $ ansible doge0* -m setup -i ./hosts Get remote system info into variables with the setup module
60. Conditionals - name: Check curl is present apt: pkg=curl when: ansible_os_family == "Debian" sudo: True main.yml http://docs.ansible.com/playbooks_conditionals.html To use if/else style you need 2 tasks with 1 when in each one
61. Conditionals - name: Check curl is present apt: pkg=curl when: ansible_os_family == "Debian" sudo: True main.yml http://docs.ansible.com/playbooks_conditionals.html To use if/else style you need 2 tasks with 1 when in each one Thats a fact!
62. Loops The task iterates over the with_items list assignin in item var http://docs.ansible.com/playbooks_loops.html - name: add several users user: name={{ item }} state=present groups=wheel with_items: - testuser1 - testuser2 - testuser3 main.yml
63. Loops ++ You can use Python types, like lists or dicts vars: users: doge: name: Doge Shibe telephone: 123-456-7890 grumpy cat: name: Tard Sauce telephone: 987-654-3210 tasks: - name: Print phone records debug: msg="User {{ item.key }} is {{ item.value.name }} ({{ item.value.telephone }})" with_dict: users main.yml You can register a dict or list result
64. Loops ++ You can use Python types, like lists or dicts vars: users: doge: name: Doge Shibe telephone: 123-456-7890 grumpy cat: name: Tard Sauce telephone: 987-654-3210 tasks: - name: Print phone records debug: msg="User {{ item.key }} is {{ item.value.name }} ({{ item.value.telephone }})" with_dict: users main.yml You can register a dict or list result Is a hash of hashes! Variables in strings use {{ }} Variables outside strings don’t use notation
65. Notifications tasks: - name: template configuration file template: src=template.j2 dest=/etc/foo.conf notify: - restart memcached - restart apache handlers: - name: restart memcached service: name=memcached state=restarted - name: restart apache service: name=apache state=restarted main.yml Trigger tasks with notify to exec the handlers section tasks Only notified when the task has changed something in the remote host
66. Includes - name: placeholder foo command: /bin/foo - name: placeholder bar command: /bin/bar tasks/foo.yml You can pass varaibles in include statements http://docs.ansible.com/playbooks_roles.html tasks: - include: tasks/foo.yml main.yml
67. ansible.cfg Change Ansible settings as you wish http://docs.ansible.com/intro_configuration.html [defaults] jinja2_extensions=jinja2.ext.do host_key_checking = False roles_path=../../ansible-roles/roles:../../ansible-private/roles:../../ansible-roles/ ansible.cfg
68. 2nd example ANSIBLE PLAYBOOK
69. Port our commands to an Ansible playbook main.yml Run in all the hosts ansible-playbook ./main.yml -i./hosts https://github.com/slok/devops-course/tree/master/03
70. Playbook COMMON PATTERNS
71. Selection by OS - name: Install the nginx packages yum: name={{ item }} state=present with_items: redhat_pkg when: ansible_os_family == "RedHat" - name: Install the nginx packages apt: name={{ item }} state=present update_cache=yes with_items: ubuntu_pkg when: ansible_os_family == "Debian" main.yml Good practice is to group tasks by OS and use include
72. Service restart tasks: - name: template configuration file template: src=template.j2 dest=/etc/foo.conf notify: - restart memcached - restart apache handlers: - name: restart memcached service: name=memcached state=restarted - name: restart apache service: name=apache state=restarted main.yml Good practice is to use handlers for final tasks (if makes sense)
73. Bulk pkg install - name: Install dependencies apt: pkg={{ item }} state=latest with_items: - linux-image-extra-{{ ansible_kernel }} - python-pycurl - git - python - python-dev main.yml
74. Change true/false - name: Create virtualenvs shell: if test -d {{ virtualenv_prefix }}/{{ item }}; then echo "false"; else virtualenv {{ virtualenv_prefix }}/{{ item }}; fi register: virtualenv_out changed_when: "virtualenv_out.stdout.find('false') == -1" with_items: virtualenvs_to_create main.yml Modules are prepared for change. Shell, command … no Use register, bash scripting and changed_when for custom cmds
75. Tags - name: Install virtualenv pip: name=virtualenv version={{ virtualenv_version }} sudo: true tags: - python - virtualenv - install main.yml Use --tags with ansible-playbook to execute specific tasks http://docs.ansible.com/playbooks_tags.html
76. Debugging - debug: msg="System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}" - name: Display all variables/facts known for a host debug: var=hostvars[inventory_hostname] main.yml Use debug and register to watch results Use -vvvv with ansible-playbook to watch results http://docs.ansible.com/debug_module.html
77. Exec task with user - name: Create virtualenvs shell: if test -d {{ virtualenv_prefix }}/{{ item }}; then echo "false"; else virtualenv {{ virtualenv_prefix }}/{{ item }}; fi register: virtualenv_out changed_when: "virtualenv_out.stdout.find('false') == -1" with_items: virtualenvs_to_create # this is needed to execute the command as different user sudo: true sudo_user: "{{ virtualenv_user }}" main.yml Use sudo and sudo_user at task level to run with an specific user
78. Exec task with env var - name: Collect static files django_manage: command: collectstatic app_path: "{{ item.value.app_dir }}" virtualenv: "{{ item.value.virtualenv }}" environment: SYSTEM_ENV: "{{ system_env_vars['SYSTEM_ENV'] }}" with_dict: deployment_apps main.yml enviroment module only applies var per task, they are ephimeral
79. delegate_to http://docs.ansible.com/playbooks_delegation.html - name: Check DNS sudo: no delegate_to: “{{ checkerserver }}” action: shell dig +short "{{ ansible_hostname |lower }}".company.tld register: in_dns main.yml Used for deployments for local actions use local_action don’t use 127.0.0.1 as host
80. wait_for http://docs.ansible.com/wait_for_module.html - name: Wait for webserver to come up wait_for: host=127.0.0.1 port=80 state=started timeout=80 main.yml Used for deployments
81. serial - name: test play hosts: webservers serial: 3 main.yml Used for deployments http://docs.ansible.com/playbooks_delegation.html
82. max_fail_porcentage - hosts: webservers max_fail_percentage: 30 serial: 10 main.yml Used for deployments http://docs.ansible.com/playbooks_delegation.html By default, ansible will contiue executing until all host fail
83. Ansible Templates
84. http://jinja.pocoo. org/docs/ # TYPE DATABASE USER ADDRESS METHOD # Default: {% for connection in postgresql_pg_hba_default %} # {{connection.comment}} {{connection.type}} {{connection.database}} {{connection.user}} {{connection.address}} {{connection.method}} {% endfor %} # Password hosts {% for host in postgresql_pg_hba_passwd_hosts %} host all all {{host}} password {% endfor %} # Trusted hosts {% for host in postgresql_pg_hba_trust_hosts %} host all all {{host}} trust {% endfor %} # User custom {% for connection in postgresql_pg_hba_custom %} # {{connection.comment}} {{connection.type}} {{connection.database}} {{connection.user}} {{connection.address}} {{connection.method}} {% endfor %} templates/pg_hba.conf.j2
85. Ansible Vault
86. Encrypt sensible data track in VCS safely “Transparent” for Ansible http://docs.ansible.com/playbooks_vault.html
87. Vault password: Confirm Vault password: $ ansible-vault create test.yml $ANSIBLE_VAULT;1.1;AES256 36643432343437396632343561616463653433313165653965306538303264663761353238316331 3364373564653735633966336137643262393036356637640a646365653839333762373361663365 66343061386137396138656166303238333730323133343730636531633831663534613533373465 3135323962376634630a333030613461643761653132653462666466306161363438313633653638 3865 $ cat ./test.yml Vault password: Decryption successful $ ansible-vault decrypt test.yml Python rules! $ cat ./test.yml
88. ... $ ansible all -m setup -i ./hosts --vault-password-file ./pass.txt

95. Ansible Galaxy downloading role 'mysql', owned by Ansibles no version specified, installing v1.0.2 - downloading role from https://github.com/Ansibles/mysql/archive/v1.0.2.tar.gz - extracting Ansibles.mysql to /home/slok/. virtualenvs/ansible/playbooks/roles/Ansibles.mysql Ansibles.mysql was installed successfully $ ansible-galaxy install Ansibles.mysql Find, share and reuse roles with ansible-galaxy Use the downloaded role as a regular one passing vars https://galaxy.ansible.com
96. Ansible & VAGRANT
97. Simple “*nix only” http://docs.vagrantup.com/v2/provisioning/ansible.html
98. config.vm.provision "ansible" do |ansible| ansible.playbook = "main.yml" ansible.inventory_path = "hosts-dev" ansible.verbose = "v" ansible.host_key_checking = false #ansible.extra_vars = { # private_key: "/my/ssh/key" # Default ~/.ssh/id_rsa #} end Vagrantfile extra_vars is where we pass our custom variables
99. Ansible REAL EXAMPLE
100. Ask for favors Do favors Gain reputation Exchange favors
101. Python Django Postgres https://github.com/slok/favorshare
102. Step 0 CREATE THE DEVBOX
103. https://github.com/slok/favorshare-devbox Vagrant file Ports 8000 & 5432 Share project folder Ubuntu trusty (1)
104. Roles Configuration Virtualenv Postgres Virtualenvwrapper https://github.com/slok/favorshare-devbox/provision
105. Structure . ├── ansible.cfg ├── inventory │ ├── group_vars │ │ ├── db │ │ ├── local │ │ └── web │ └── hosts-dev ├── main.yml └── roles ├── common │ └── tasks │ └── main.yml └── virtualenvwrapper ├── defaults │ └── main.yml └── tasks └── main.yml $ tree .
106. Ansible config [defaults] # Don't add to known_hosts (will be changing all the time) host_key_checking = False ansible.cfg Don’t use “host_key_checking = False” in non devboxes Not checking and storing the server keys is faster
107. Hosts # We know this from the Vagrantfile, but we could do dynamically devbox.favorshare.org ansible_ssh_host=192.168.100.50 [web] devbox.favorshare.org [db] devbox.favorshare.org # Our env group is local [local:children] web db inventory/hosts-dev The groups will be used for limiting and variable grouping
108. Group vars remote_user: "vagrant" ansible_ssh_user: "vagrant" ansible_ssh_private_key_file: ~/.vagrant.d/insecure_private_key inventory/group_vars/local # Virtualenv role settings (https://galaxy.ansible.com/list#/roles/347) virtualenv_version: 1.11.6 inventory/group_vars/web # Postgresql role settings (https://galaxy.ansible.com/list#/roles/512) postgresql_databases: - {'name': "favorshare"} inventory/group_vars/db Grouping the variables in independent files is a good practice
109. main - name: Common tasks in all servers hosts: all sudo: true roles: - common tags: - pre - common - name: Install virtualenv hosts: web sudo: true roles: - brad.virtualenv tags: - python - virtualenv - name: Install virtualenvwrapper hosts: web sudo: true roles: - virtualenvwrapper tags: - python - virtualenvwrapper - name: Install Postgres hosts: db sudo: true roles: - Ansibles.postgresql tags: - db - postgresql main.yml
110. main - name: Common tasks in all servers hosts: all sudo: true roles: - common tags: - pre - common - name: Install virtualenv hosts: web sudo: true roles: - brad.virtualenv tags: - python - virtualenv - name: Install virtualenvwrapper hosts: web sudo: true roles: - virtualenvwrapper tags: - python - virtualenvwrapper - name: Install Postgres hosts: db sudo: true roles: - Ansibles.postgresql tags: - db - postgresql main.yml Groups
111. Common - name: Update repos apt: update_cache=yes when: ansible_os_family == "Debian" - name: Bulk dependency installation apt: pkg: "{{ item }}" state: present when: ansible_os_family == "Debian" with_items: - build-essential - python-dev - python - python-pip roles/common/tasks/main.yml Is good to have a common role as the first role of the playbook
112. Virtualenv downloading role 'virtualenv', owned by brad no version specified, installing master - downloading role from https://github.com/brad/ansible-virtualenv/archive/master.tar.gz - extracting brad.virtualenv to /home/slok/.virtualenvs/ansible/playbooks/roles/brad. virtualenv brad.virtualenv was installed successfully $ ansible-galaxy install brad.virtualenv https://galaxy.ansible.com/list#/roles/347 # Virtualenv role settings (https://galaxy.ansible.com/list#/roles/347) virtualenv_version: 1.11.6 inventory/group_vars/web
113. Virtualenwrapper - name: Install virtualenvwrapper pip: name=virtualenvwrapper - name: Add virtualenvwrapper to bashrc lineinfile: dest: "{{ item.0.location }}" line: "{{ item.1 }}" with_subelements: - virtualenvwrapper_configuration - config roles/virtualenvwrapper/tasks/main.yml virtualenvwrapper_configuration: - location: "/home/{{ remote_user }}/.bashrc" config: - "export WORKON_HOME=$HOME/.virtualenvs" - "export PROJECT_HOME=$HOME/projects" - "source /usr/local/bin/virtualenvwrapper.sh" roles/virtualenvwrapper/defaults/main.yml with_subelements loop style is very powerful
114. Postgresql downloading role 'postgresql', owned by Ansibles no version specified, installing v1.0.3 - downloading role from https://github.com/Ansibles/postgresql/archive/v1.0.3.tar.gz - extracting Ansibles.postgresql to /home/slok/.virtualenvs/ansible/playbooks/roles/Ansibles. postgresql Ansibles.postgresql was installed successfully $ ansible-galaxy install brad.virtualenv https://galaxy.ansible.com/list#/roles/512 # Postgresql role settings (https://galaxy.ansible.com/list#/roles/512) postgresql_databases: - {'name': "favorshare"} inventory/group_vars/db
115. ansible-playbook ./main.yml -i inventory/
116. Vagrant + Ansible # Ansible all the things! config.vm.provision "ansible" do |ansible| ansible.playbook = "provisioning/main.yml" ansible.inventory_path = "provisioning/inventory" ansible.verbose = "v" # Check this https://github.com/mitchellh/vagrant/issues/3096 ansible.limit = 'local' end Vagrantfile Pay attention to “limit” param in Vagrant >= 1.5
