It is possible to set variables at the command line using the –extra-vars (or -e) argument. Variables can be defined using a single quoted string (containing one or more variables) using one of the formats below.<\/p>\n\n\n\n
\nkey=value<\/p>\n<\/blockquote>\n\n\n\n
Method 1<\/strong><\/p>\n\n\n
$ ansible-playbook release.yml --extra-vars \"version=1.23.45 other_variable=foo\"<\/span>\n$ ansible-playbook release.yml -e \"version=1.23.45 other_variable=foo\"<\/span>\n\nIn your yml file you assign these to scoped ansible variables by doing something like:\n\nvars:\n my_version: \"{{ version }}\"<\/span>\n my_other_variable<\/span>: {{ other_variable }}\n<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\nMethod 2<\/strong>
An alternative to using command line args is to utilise environmental variables that are already defined within your session, you can reference these within your ansible yml files like this:<\/p>\n\n\n# To set a environmental variables<\/span>\n$ export version=1.23<\/span>.45<\/span>\n$ export other_variable=foo\"\n\nvars:\n my_version: \"<\/span>{{ lookup('env'<\/span>, 'version'<\/span>) }}\"\n my_other_variable: {{ lookup('env', 'other_variable') }}\n<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\nMethod 3<\/strong>
If you are passing variables from a file, you need a second –extra-vars flag to pass variables.<\/p>\n\n\n$ ansible-playbook release.yml --extra-vars \"@some_file.json\"<\/span>\n$ ansible-playbook release.yml -e \"@some_file.json\"<\/span>\n$ ansible-playbook release.yml --extra-vars \"version=1.23.45 other_variable=foo\"<\/span> --extra-vars \"@some_file.json\"<\/span>\n$ ansible-playbook release.yml -e \"version=1.23.45 other_variable=foo\"<\/span> --extra-vars \"@some_file.json\"<\/span><\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\nMethod 4<\/strong>
How can I pass yaml array to –extra-vars in Ansible playbook?<\/p>\n\n\n\nTo answer your first question “How can I pass yaml array to –extra-vars in Ansible playbook.” you can pass in a json formatted string to extra-vars.<\/p>\n\n\n\n
Here is an example play:<\/p>\n\n\n
- hosts: all\n gather_facts<\/span>: no\n tasks<\/span>:\n - debug: var<\/span>=test_list\n\nAnd how to pass in<\/span> test_list to ansible-playbook:\n$ ansible-playbook -c local -i localhost, test.yml --extra-vars='{\"test_list\": [1,2,3]}'<\/span><\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\nMethod 5 – PASSING MULTIPLE VARIABLES.<\/strong><\/p>\n\n\n
$ ansible-playbook extra_var_multiple.yml --extra-var<\/span> \"my_var1=CoolVar1 my_var2=WarmVar2\"<\/span>\n\nPASSING VARIABLES CONTAINING SPACES.\n$ ansible-playbook extra_var_single.yml -e \"my_var='Very Hot Var with spaces'\"<\/span>\n\n#PASSING INTEGER, BOOL, LIST, OR ANY OTHER NON-STRING VALUES.<\/span>\nansible-playbook extra_var_json.yml -e '{\"my_float\": 1.618, \"my_list\": [\"HGTTG\", 42], \"my_string\": \"Time is an illusion.\"}'<\/span>\n\n#PASSING JSON FORMATTED VARIABLES SAVED IN A FILE<\/span>\n[przemek@quasar extra_var]$ cat extra_vars.json\n{\"my_float\"<\/span>: 1.618<\/span>, \"my_list\"<\/span>: [\"HGTTG\"<\/span>, 42<\/span>], \"my_string\"<\/span>: \"Time is an illusion.\"<\/span>}\n\nansible-playbook extra_var_json.yml -e \"@extra_vars.json\"<\/span>\n<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\nReference<\/strong>
