When I assign a variable containing double quotes to another variable the double quotes " sometimes get converted to single quotes '.

This appears to happen when the variable contents look like valid JSON. This is a known issue, and related to the interaction between Ansible and Jinja2. Jinja2 has historically only allowed returning strings, so we have some code to attempt to convert things that look like python data structures, into actual python data structures.

We have merged a new feature that is toggled off by default for now to utilize new Jinja2 native types. This feature will be included in the upcoming 2. If you are interested in a more verbose explanation of what is happening, see comment. Skip to content.

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.

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.

If the variable value does not contain a hash, no quotes are added. I expected either both variables to have quotes added, or both variables to not have quotes added. The root password contained no hash. So ansible was able to create the user perfectly fine, but when I attempted to login using the mysql commandline clientI was unable to do so unless I added a set of double quotes " around the password. Removing the quotes on both the variable values in the inventory file fixes the issue for me, but I still believe behavior should be consistent when the quotes are present.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am a little confused though, as in some files I see strings in double quotes and in some without.

A few points to consider:. After a brief review of the YAML cookbook cited in the question and some testing, here's my interpretation:. Seems to me that the best approach would be to not use quotes unless you have to, and then to use single quotes unless you specifically want to process escape codes.

Asked 6 years, 6 months ago. Active 1 year, 6 months ago. Viewed k times. A few points to consider: example 1 - all strings use double quotes; example 2 - no strings except the last two use quotes; the YAML cookbook says: Enclosing strings in double quotes allows you to use escapings to represent ASCII and Unicode characters. Does this mean I need to use double quotes only when I want to escape some characters?

My question is: what are the rules for using the different types of quotes in YAML? Could it be said that: in general, you don't need quotes; if you want to escape characters use double quotes; use! Alex Popov Alex Popov Second link is not working anymore, I suggest to put your examples into the question. Active Oldest Votes. After a brief review of the YAML cookbook cited in the question and some testing, here's my interpretation: In general, you don't need quotes.

Use quotes to force a string, e. Use quotes if your value includes special characters, e. Single quotes let you put almost any character in your string, and won't try to parse escape codes. Double quotes parse escape codes. The exclamation mark introduces a method, e. Update "Yes" and "No" should be enclosed in quotes single or double or else they will be interpreted as TrueClass and FalseClass values: en: yesno: 'yes': 'Yes' 'no': 'No'.

Mark Berry Mark Berry That's not quite the full picture. I wasn't trying to provide the full picture, just some rules of thumb. Yes, it looks like sometimes, some special characters reserved indicators can be used without quotes as long as a reserved indicator doesn't start a plain scalarbut it's not wrong to use quotes whenever you see a special character.

The rules for strings in YAML are insanely complicated, because there are so many different types of strings. I wrote up a table here: stackoverflow. Also, here's a quite complete reference I wrote: blogs.This guide will walk you through taking a helm chart, and creating an Ansible operator using memcached as an example. To follow along with our example operator:. Copy the files from github.

This is a list of tasks Ansible will run that will create the various kubernetes objects that make up your application deployment, service, ingress, pvc, etc. The rule of thumb here is if your helm chart has a template for it, it should be a task in this file, unless it's the service account, role, or role binding that makes up the operator itself.

These can be created easily from the templates your helm chart uses, with one task per templated yaml. The below example shows the syntax. The task's name can be anything you want, but should clearly state what the task creates. Double-check that anything you paste into the file is properly indented.

Remove the. If you have existing variable names that begin with something else. Any template variables should be changed to normal variables. Make a note of these for later. Here, you can see the changes made. The original lines are commented out above the new formatting.

Remove the "template" and ". Drop the leading ". Make a note of the new variables:. In the metadata field for each task, add a declaration for namespace. In general, this should be set to the Ansible variable "meta. Add a reference to the namespace. Make sure your imagePullPolicy for any containers is set to your variable or define it directly to "Always", "Never" or "IfNotPresent".

Check the imagePullPolicy. You can copy your values. Copy the values. This will take care of defining any variable that started with ". However, all the variables that you took note of before that didn't start with.

Add a definition for the variables we noted earlier. The best practice is to create a variable set to one of these values.

Connecting the Ansible Logic.This page provides a basic overview of correct YAML syntax, which is how Ansible playbooks our configuration management language are expressed. Further, there are libraries available in most programming languages for working with YAML.

You may also wish to read Working With Playbooks at the same time to see how this is used in practice. So, we need to know how to write lists and dictionaries in YAML. All YAML files regardless of their association with Ansible or not can optionally begin with and end with This is part of the YAML format and indicates the start and end of a document. All members of a list are lines beginning at the same indentation level starting with a "- " a dash and a space :. A dictionary is represented in a simple key: value form the colon must be followed by a space :.

More complicated data structures are possible, such as lists of dictionaries, dictionaries whose values are lists or a mix of both:. In either case the indentation will be ignored. Examples are:. This really has nothing to do with Ansible, but will give you a feel for the format:. While you can put just about anything into an unquoted scalar, there are some exceptions.

A colon followed by a space or newline ": " is an indicator for a mapping. A space followed by the pound sign " " starts a comment. The difference between single quotes and double quotes is that in double quotes you can use escapes:. If your value starts with a quote the entire value must be quoted, not just part of it.

Here are some additional examples of how to properly quote things:. You should also be aware of? Boolean conversion is helpful, but this can be a problem when you want a literal yes or other boolean values as a string.

In these cases just use quotes:. YAML converts certain strings into floating-point values, such as the string 1. If you need to specify a version number in a requirements. Ansible 2.
