Jinja template rendering is supported in container. Your container. Variable definitions are needed for Jinja to resolve expressions. Resolving Jinja expressions to render the final container. See Passing environment variablesTop-level defaultsPassing variable filesand Variable precedence for a deeper discussion of variables. For example, the following passes a YAML file, devel. Suppose devel.

Variables can be defined as simple string, integer, or float types, or they can be complex data structures. Before the build command can be executed, Jinja is called to perform template rendering. Ansible Container reads the contents of the variable file, devel. Jinja performs the transformation, returning a copy of container. The following is the transformed container. Pass the path to a file containing variable definitions using the --vars-file option.

The file path must be one of the following:. When --vars-file is passed, Ansible Container checks if the path is an absolute path to a file. If not, it checks for the file relative to the project path, which is the current working directory or a path specified using the --project option.

If the file is still not found, it looks for the file relative to the ansible folder within the project path. For example:. The filename extension determines how the file is parsed. If the name ends with. Variable definitions can also be provided as environment variables.

Use the top-level defaults section to define default values, as demonstrated in the following example:. Prior to resolving variables at the service level, a global set of variables is formed using environment variables, top-level defaultsand any variable files.

The order of precedence here is given first to environment variables, then variable files, and finally to top-level defaults. In other words, top-level defaults receive the lowest precedence, and environment variables receive the highest.

At the service level, role variables and role metadata come into play. Precedence is given first to values defined for the service in container. Note Resolving Jinja expressions to render the final container. The file path must be one of the following: Absolute file path Relative to the project path Relative to the ansible folder When --vars-file is passed, Ansible Container checks if the path is an absolute path to a file.Released: Apr 13, View statistics for this project via Libraries.

Jinja is a fast, expressive, extensible templating engine. Special placeholders in the template allow writing code similar to Python syntax.

Then the template is passed data to render the final document. Install and update using pip :.

Since jinja2 templates are compiled to Python files the approach should be similar to how mako template coverage is currently measured. Though, in mako there is a handy ModuleInfo class that provides a template source code map that helps to measure the template code coverage.

Is there anything similar in jinja2 or should I use the meta API? Would appreciate any pointers. Stackoverflow post as a reference: Jinja2 template compilation information.

Due to some removed behavior inmore lines now have coverage since they aren't compiled into a mult-line format string expression. At this point I think there's two similar issues that need to be addressed:.

Feature: Coverage support on templates At this point I think there's two similar issues that need to be addressed: The lexer and parser treat template data across line breaks as a single node. If someone figures out how to record the start and end line for each node, that will go a long way towards getting the information we need for full coverage.

The compiler treats groups of nodes that can be converted to constant data at compile time as a single line of output code. This was referenced Jan 24, Template coverage discussion Sign up for free to join this conversation on GitHub.

Thanks for taking the time to open this issue. In order for the community to handle your issue effectively, we need a bit more information.

Hello everyone, I'm also affected by this bug, cassandra only tolerates single quotes in its json format for replication strategy. I can't figure a way to replace double quotes by single quotes in the following playbook. If you are still interested in this, please create a new issue with the requested information.

Hello ansibotdev I provided the info instead of cthiemann Please reopen! For the people who had this bug, could i ask you if you use a version install via pip or via package manager? I had exactly the same behavior and lost many hours to finally found that the problem only occur if i use ansible installed via pip.

The most basic usage of Jinja in state files is using control structures to wrap conditional or redundant state elements:.

In this example, the first if block will only be evaluated on minions that aren't running FreeBSD, and the second block changes the file name based on the os grain. Writing if-else blocks can lead to very redundant state files however. In this case, using pillarsor using a previously defined variable might be easier:. Using a variable set by the template, the for loop will iterate over the list of MOTD files to update, adding a state block for each file.

Includes and imports can be used to share common, reusable state configuration between state files and between files. This would import the test template variable or macro, not the test state element, from the file lib. In the case that the included file performs checks against grains, or something else that requires context, passing the context into the included file is required:.

Macros are helpful for eliminating redundant code. Macros are most useful as mini-templates to repeat blocks of strings with a few parameterized variables. Be aware that stripping whitespace from the template block, as well as contained blocks, may be necessary to emulate a variable return from the macro. This would define a macro that would return a string of the full package name, depending on the packaging system's naming convention. The whitespace of the macro was eliminated, so that the macro would return a string without line breaks, using whitespace control.

Template inheritance works fine from state files and files. The search path starts at the root of the state tree or pillar. Saltstack allows raising custom errors using the raise jinja function.

When rendering the template containing the above statement, a TemplateError exception is raised, causing the rendering to fail with the following message:. Saltstack extends builtin filters with these custom filters:. Converts any time related object into a time based string. It requires valid strftime directives. An exhaustive list can be found here in the Python documentation. Fuzzy dates require the timelib Python module is installed. Serializes a single object into a YAML scalar with any necessary handling for escaping special characters.

This will work for any scalar YAML data type: ints, floats, timestamps, booleans, strings, unicode. It will not work for multi-objects such as sequences or maps.

Serializes a string into a properly-escaped YAML double-quoted string. This is useful when the contents of a string are unknown and may contain quotes or unicode that needs to be preserved.

The resulting string will be emitted with opening and closing double quotes. Scan through string looking for a location where this regular expression produces a match. Returns None in case there were no matches found. If zero or more characters at the beginning of string match this regular expression, otherwise returns None.I needed this to work and discovered that running the following using 2 backward slashes works for me when rendering within a jinja template "however" when running the following code it outputs correctly to stdout when using 4 backward slashes.

Doubling double back-slash worked for me : Item : ["intl","mysqlnd","curl","ldap","gd","dom"].

The problem: I wanted to use the jinja 'map' filter to modify each item in a string, in this simple example, adding '.

Unfortunately, it uses 'value' as the pattern. So it's the wrong way around. The following example creates a simple filter that has the format args in an order we can use when calling 'map'. Note this is extremely simplestic, and only allows for adding a prefix or suffix to an item. This comment has been minimized. Sign in to view. Copy link Quote reply.

See builtin filters in the official Jinja2 template documentation.

In addition the ones provided by Jinja2, Ansible ships with its own and allows users to add their own custom filters.

The following filters will take a data structure in a template and render it in a slightly different format. These are occasionally useful for debugging:. That causes unexpected line break after 80th symbol if there is a space after 80th symbol To avoid such behaviour and generate long lines it is possible to use width option:.

Note that it also supports passing through other YAML parameters. The default behavior from ansible and ansible. The variable value will be used as is, but the template evaluation will raise an error if it is undefined. If you want to use the default value when variables evaluate to false or an empty string you have to set the second parameter to true :.

As of Ansible 1. In this example, the default None Python null value will cause the later filters to fail, which will trigger the or omit portion of the logic. This filter turns a list of dicts with 2 keys, into a dict, mapping the values of those keys into key: value pairs:. This is the reverse of the dict2items filter. To get a list combining the elements of other lists use zip :.

Similarly to the output of the items2dict filter mentioned above, these filters can be used to construct a dict :. Produces a product of an object, and subelement values of that object, similar to the subelements lookup:. An example of using this filter with loop :.

As of Ansible version 2. This way, you can create random-but-idempotent MAC addresses:. This filter can be used similar to the default jinja2 random filter returning a random item from a sequence of itemsbut can also generate a random number based on a range.

This way, you can create random-but-idempotent numbers:. All you need is a seed.
