How to create yml file in windows?

Create a YAML file with the configured that your build pipeline will use. This will be custom to your requirements. The sample here shows a YAML file configured to the Bot Framework Solutions repository.

YAML Ain't Markup Language (YAML) is a data serialization language that is consistently listed as one of the most popular programming languages. It's often used as a format for configuration files, but its object serialization abilities make it a viable replacement for languages like JSON. This YAML tutorial will demonstrate the language syntax with a guide and some simple coding examples in Python. YAML has broad language support and maps easily into native data structures. It's also easy for humans to read, which is why it's a good choice for configuration. The YAML acronym was shorthand for Yet Another Markup Language. But the maintainers renamed it to YAML Ain't Markup Language to place more emphasis on its data-oriented features.

Let's take a look at a YAML file for a brief overview.

The file starts with three dashes. These dashes indicate the start of a new YAML document. YAML supports multiple documents, and compliant parsers will recognize each set of dashes as the beginning of a new one. Next, we see the construct that makes up most of a typical YAML document: a key-value pair. The “doe” is a key that points to a string value: “a deer, a female deer”. YAML supports more than just string values. The file starts with six key-value pairs. They have four different data types. “doe” and “ray” are strings. The “pi” is a floating-point number. The “xmas” is a boolean. The “french-hens” is an integer. You can enclose strings in single(‘) or double-quotes(“) or no quotes at all. YAML recognizes unquoted numerals as integers or floating point. The seventh item is an array. The “calling-birds” has four elements, each denoted by an opening dash. I indented the elements in “calling-birds” with two spaces. Indentation is how YAML denotes nesting. The number of spaces can vary from file to file, but tabs are not allowed. We'll look at how indentation works below. Finally, we see “xmas-fifth-day”, which has five more elements inside it, each of them indented. We can view “xmas-fifth-day” as a dictionary that contains two string, two integers, and another dictionary. YAML supports nesting of key-values, and mixing types. Before we take a deeper dive, let's look at how this document looks in JSON. I'll throw it in this handy JSON to YAML converter.

JSON and YAML have similar capabilities, and you can convert most documents between the formats.

Whitespace is part of YAML's formatting. Unless otherwise indicated, newlines indicate the end of a field. You structure a YAML document with indentation. The indentation level can be one or more spaces. The specification forbids tabs because tools treat them differently. Consider this document. The items inside are indented with two spaces.

Let's take a look at how a simple python script views this document. We'll save it as a file named foo.yaml. The PyYAML package will map a YAML file stream into a dictionary. We'll iterate through the outermost set of keys and values and print the key and the string representation of each value. You can find a processor for your favorite platform here.

The output is:

When we tell python to print a dictionary as a string, it uses the inline syntax we'll see below. We can see from the output that our document is a python dictionary with two strings and another dictionary nested inside it. YAML's simple nesting gives us the power to build sophisticated objects. But that's only the beginning.

Comments begin with a pound sign. They can appear after a document value or take up an entire line.

Comments are for humans. YAML processors will discard them.

Values in YAML's key-value pairs are scalar. They act like the scalar types in languages like Perl, Javascript, and Python. It's usually good enough to enclose strings in quotes, leave numbers unquoted, and let the parser figure it out. But that's only the tip of the iceberg. YAML is capable of a great deal more.

The key-value is YAML's basic building block. Every item in a YAML document is a member of at least one dictionary. The key is always a string. The value is a scalar so that it can be any datatype. So, as we've already seen, the value can be a string, a number, or another dictionary.

YAML recognizes numeric types. We saw floating point and integers above. YAML supports several other numeric types. An integer can be decimal, hexadecimal, or octal.

Let's run our python script on this document.

As you expect, Ox indicates a value is hex, and a leading zero denotes an octal value. YAML supports both fixed and exponential floating point numbers.

When we evaluate these entries we see:

Finally, we can represent not-a-number (NAN) or infinity.

The value of foo is infinity. Bar is negative infinity, and plop is NAN.

YAML strings are Unicode. In most situations, you don't have to specify them in quotes.

Our test program processes this as:

But if we want escape sequences handled, we need to use double quotes.

YAML processes the first value as ending with a carriage return and linefeed. Since the second value is not quoted, YAML treats the \n as two characters.

YAML will not escape strings with single quotes, but the single quotes do avoid having string contents interpreted as document formatting. String values can span more than one line. With the fold (greater than) character, you can specify a string in a block.

But it's interpreted without the newlines.

The block (pipe) character has a similar function, but YAML interprets the field exactly as is.

So, we see the newlines where they are in the document.

You enter nulls with a tilde(~) or the unquoted null string literal.

Our program prints:

Python's representation for null is None.

YAML indicates boolean values with the keywords True, On and Yes for true. False is indicated with False, Off, or No.

You can specify arrays or lists on a single line.

Or, you can put them on multiple lines.

The multiple line format is useful for lists that contain complex objects instead of scalars.

An array can contain any valid YAML value. The values in a list do not have to be the same type.

We covered dictionaries above, but there's more to them. Like arrays, you can put dictionaries inline. We saw this format above. It's how python prints dictionaries.

We've seen them span lines before.

And, of course, they can be nested and hold any value.

Multiline values may end with whitespace, and depending on how you want the document to be processed you might not want to preserve it. YAML has the strip chomp and preserve chomp operators. To save the last character, add a plus to the fold or block operators.

So, if the value ends with whitespace, like a newline, YAML will preserve it. To strip the character, use the strip operator.

A document starts with three dashes and ends with three periods. Some YAML processors require the document start operator. The end operator is usually optional. For example, Java's Jackson will not process a YAML document without the start, but Python's PyYAML will. You'll usually use the end document operator when a file contains multiple documents. Let's modify our python code.

PyYAML's load_all will process all of the documents in a stream. Now, let's process a compound document with it.

The script finds two YAML documents.

YAML is a powerful language that can be used for configuration files, messages between applications, and saving application state. We covered its most commonly used features, including how to use the built-in datatypes and structure complex documents. Some platforms support YAML's advanced features, including custom data types.

YAML or ‘Yet Another Markup Language’ is a human-readable data serialization language. It is designed in order to be both human-readable and also efficient for parsing.

The YAML specification was written in 2006 by David Preshing, the creator of PHP Markdown, who wanted a universal markup language that was easy for humans to read and write, but still allowed for significant information density and reasonable balancing of tradeoffs between the machine time required to process it and the machine time required to produce it.

These are 3 ways to create a new YAML File.

YAML is mostly used for the configuration files. So to avoid mistakes, find the right template for the YAML configuration for Kubernetes, Ansible or CircleCI.

Here is an example of the Kubernetes nginx configuration deployment file.

Use this YAML validator tool to validate the YAML

I hope this article helps you to understand basic ways to make or create valid YAML files and beautify them.

The config.yml file drives the creation of the cluster. It uses YAML syntax which is stored as readable text. As config.yml is a Linux file, lines must terminate with a line feed character (/n). If using a windows editor to create or edit the file, be sure to use an editor such as Open Office which supports saving text files with new line characters or use dos2unix to convert the windows text file to linux format.

YAML files support data structures such as lists, dictionaries and scalars. A complete definition of the config.yml file along with detailed documentation of the elements used are given in appendix B.

The config.yml file has 4 main sections. These are;
