ansible-playbook

问题 I want to abort execution of remaining task if certain condition is failed. and display proper error message. So instead of skipping remaining task I want to show error message and stop execution of ansible playbook. Lets say I am running below command $ ansible-playbook playbook.yml -e "param1=value1 param2=value" My playbook look like this:- playbook.yml:- --- - hosts: local user: roop gather_facts: no vars: {param1: "", param2: ""} tasks: #check whether param1 defined - name: 'Check for

问题 Is it possible to reuse a role in a role? I do not mean via defining a dependency in the meta/main.yml file of a role but by including the role in the tasks/main.yml of another role directly? For example, I define a couple of basic roles in rolebooks and some more high level roles in roles. I want the high level roles to include some of the basic roles in addition to some specific tasks. playbooks/ rolebooks/ some_role/ roles/ webtier/ tasks/ main.yml In playbooks/roles/webtier/tasks/main.yml

问题 I have this error when I launch my playbook against the localhost host. TASK [setup] ******************************************************************* fatal: [127.0.0.1]: UNREACHABLE! => {"changed": false, "msg": "SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue", "unreachable": true} to retry, use: --limit @deploy-test-env.retry PLAY RECAP ******************************

问题 I have this play.yml --- - hosts: 127.0.0.1 connection: local sudo: false tasks: - include: apache.yml My Apache look like this: vars: url: czxcxz - name: Download apache shell: wget {{url}} This is giving me error. If I remove vars then it works. But I want to include the vars inside tasks so that I can keep different vars for different tasks separate. 回答1: NOTE: Using set_fact as described below sets a fact/variable onto the remote servers that the task is running against. This fact

问题 Based on extra vars parameter I Need to write variable value in ansible playbook ansible-playbook playbook.yml -e "param1=value1 param2=value2 param3=value3" If only param1 passed myvariable: 'param1' If only param1,param2 passed myvariable: 'param1,param2' If param1,param2,param3 are passed then variable value will be myvariable: 'param1,param2,param3' When I try to create variable dynamically through template then my playbook always takes previous variable value. But inside dest=roles

问题 So after reading Ansible docs, I found out that Handlers are only fired when tasks report changes, so for example: some tasks ... notify: nginx_restart # our handler - name: nginx_restart vs some tasks ... register: nginx_restart # do this after nginx_restart changes when: nginx_restart|changed Is there any difference between these 2 methods? When should I use each of them? For me, register seems to have more functionality here, unless I am missing something... 回答1: There are some differences

问题 I'm using the ec2 module with ansible-playbook I want to set a variable to the contents of a file. Here's how I'm currently doing it.

问题 While doing clone, push or pull of a private git repository hosted internally (e.g. on a GitLab instance) with Ansible's Git module, how do I specify username and password to authenticate with the Git server? I don't see any way to do this in the documentation. 回答1: You can use something like this: --- - hosts: all gather_facts: no become: yes tasks: - name: install git package apt: name: git - name: Get updated files from git repository git: repo: "https://{{ githubuser | urlencode }}:{{

问题 Inside my playbook I'd like to create a variable holding the output of an external command. Afterwards I want to make use of that variable in a couple of templates. Here are the relevant parts of the playbook: tasks: - name: Create variable from command command: "echo Hello" register: command_output - debug: msg="{{command_output.stdout}}" - name: Copy test service template: src=../templates/test.service.j2 dest=/tmp/test.service - name: Enable test service shell: systemctl enable /tmp/test

问题 I'm designing a kind of playbook lib with individual tasks so in the usual roles repo, I have something like: roles ├── common │ └── tasks │ ├── A.yml │ ├── B.yml │ ├── C.yml │ ├── D.yml │ ├── login.yml │ ├── logout.yml │ └── save.yml ├── custom_stuff_workflow │ └── tasks │ └── main.yml └── other_stuff_workflow └── tasks └── main.yml my main.yml in custom_stuff_workflow then contain something like: --- - include: login.yml - include: A.yml - include: C.yml - include: save.yml - include:
