Join the community to find out what other Atlassian users are discussing, debating and creating. I'm attempting to use bitbucket pipelines to create docker images and tag them with the branch name. I've tried this both for branch builds and for custom builds that I run from the branch and in both cases the variable is empty. Here is my yaml file:. You must be a registered user to add a comment.

I use for mercurial:. It seems to me like it should work for "branches" but not "custom" builds according to this :. The branch on which the build was kicked off.

This value is only available on branches. Not available for builds against tags, or custom pipelines. However, as you stated, it doesn't appear to be set even in that case. Hi everyone, The Cloud team recently announced 12 new DevOps features that help developers ship better code, faster! You're one step closer to meeting fellow Atlassian users at your local event.

Variables give you a convenient way to get key bits of data into various parts of the pipeline. The most common use of variables is to define a value that you can then use in your pipeline.

All variables are stored as strings and are mutable. The value of a variable can change from run to run or job to job of your pipeline. When you define the same variable in multiple places with the same name, the most locally scoped variable wins.

So, a variable defined at the job level can override a variable set at the stage level. A variable defined at the stage level will override a variable set at the pipeline root level. A variable set in the pipeline root level will override a variable set in the Pipeline settings UI. Variables are different from runtime parameterswhich are typed and available during template parsing. When you define a variable, you can use different syntaxes macro, template expression, or runtime and what syntax you use will determine where in the pipeline your variable will render.

In YAML pipelines, you can set variables at the root, stage, and job level. When you set a variable in the UI, that variable can be encrypted and set as secret. User-defined variables can be set as read-only. You can use a variable group to make variables available across multiple pipelines. You can use templates to define variables that are used in multiple pipelines in one file.

In addition to user-defined variables, Azure Pipelines has system variables with predefined values. If you are using YAML or classic build pipelines, see predefined variables for a comprehensive list of system variables. If you are using classic release pipelines, see release variables. System variables are set with their current value when you run the pipeline. Some variables are set automatically. As a pipeline author or end user, you change the value of a system variable before the pipeline is run.

Environment variables are specific to the operating system you are using. They are injected into a pipeline in platform-specific ways. The format corresponds to how environment variables get formatted for your specific scripting platform. System and user-defined variables also get injected as environment variables for your platform.

When variables are turned into environment variables, variable names become uppercase, and periods turn into underscores.

For example, the variable name any. User-defined variables can consist of letters, numbers. Don't use variable prefixes that are reserved by the system. These are: endpointinputsecretand securefile. Any variable that begins with one of these strings regardless of capitalization will not be available to your tasks and scripts. Azure Pipelines supports three different ways to reference variables: macro, template expression, and runtime expression.Ask the community.

Bitbucket Pipelines provides a set of default variables as well as the ability to define your own variables. Variables are configured as environment variables in the build container. You can access the variables from the bitbucket-pipelines.

The absolute path of the directory that the repository is cloned into within the Docker container. You can add, edit, or remove variables at the account, repository, and deployment environment levels.

If you use the same name as an existing variable, you can override it. Each deployment environment is independent so you can use the same variable name with different values for each environment.

Names are case-sensitive. Names can't start with a digit. Variables can't contain line breaks. Variables specified for a team or an individual account can be accessed from all repositories that belong to the team or account. You must be an administrator to manage team variables. Workspaces or individual account variables can be accessed by all users with the write permission for any repository private or public that belongs to the team or account. You must be an administrator of an account or a repository to manage variables respectively.

Variables added at the repository level can be accessed by any users with the push permission in the repository. You can also define variables so that they can only be used in a specific deployment environment. Deployment variables override both team and repository variables, and are unique to each environment.

You can secure a variable, which means it can be used in your scripts but its value will be hidden in the build logs see example below. If you want to edit a secure variable, you can only give it a new value or delete it. Secure variables are stored as encrypted values. Click the padlock to secure the variable. Pipelines masks secure variables so they are not disclosed to your team members viewing build logs. This can lead to confusion about whether secured variables are working properly, so here's an example of how it works.

The value of the variable can be used by the script, but will not be revealed in the logs.

If you have secure variable value set to a common word, that word will be replaced with the variable name anywhere it appears in the log file.

Secured variables are designed to be used for unique authentication tokens and passwords and so are unlikely to be also used in clear text. Pipelines also matches some basic encodings of the variable value, like URL encoding, to prevent variables being displayed when used in URLs.Join the community to find out what other Atlassian users are discussing, debating and creating.

I want to include special characters like quotes, backslashes, dollar signs and newlines in my pipe variables. How do I properly quote and escape them so that they survive processing by the yaml parser and variable expansion? The key to working out how to properly quote and escape pipe variables is to understand that they will undergo two rounds of processing before they make it into the pipe.

The first round is yaml parsing. The second round is variable expansion. The easiest way to deal with the first round of processing yaml parsing is to enclose the entire value of the variable in single quotes. This tells the yaml parser not to process any special characters except the closing single quote character. If you need to include a single quote character in your variable then you just need to double it. The second round of processing actually happens within your pipeline and is performed by the shell that is running your build script usually bash.

Pipe variables are passed to the pipe using command-line arguments to a "docker run" command. For example, if you define a pipe variable like this in bitbucket-pipelines. Note the double quotes around the value. This tells your shell to do a limited amount of variable expansion on the value that you've defined. That's what allows you to write something like this in your pipeline:. With this in mind, here are some examples of how to do proper quoting and escaping of pipe variables containing special characters that might otherwise get processed during yaml parsing or variable expansion.

In each case I've listed the desired string value first without any quoting or escaping followed by a yaml snippet that will produce that value. This example takes advantage of some special processing for unescaped double quote characters within Pipelines. Pipelines will automatically add a backslash character before any unescaped double quote character to keep your shell happy without this special processing this example would completely break the "docker run" command - can you see why?

Single quotes need to be doubled to survive yaml parsing. No further escaping is required for the shell. We need to escape the back ticks because they are treated specially by the shell, even within double quotes.

Even though we are enclosing our value with single quotes here which stops the yaml parser from processing backslash characters we still need to escape the backslash to avoid special processing by the shell in the second round.

Note here that we're using double quotes around the value instead of single quotes. The shell doesn't do any further processing on tab or newline characters within double quotes, so no further escaping is required.

However that means that we need extra escaping for backslash and double quote characters. In the case of a backslash we need to escape it twice - once for yaml and once for the shell, so a sequence of four backslash characters will actually end up being just a single backslash by the time your variable makes it all the way into the pipe. On the other hand, the single quote character now doesn't need any escaping at all.

And finally, here's a repository that uses all these examples in a real pipe. The pipe is designed to just run the "env" command which shows all the final variable values. You must be a registered user to add a comment.

If you've already registered, sign in. Otherwise, register and sign in. It's worth mentioning that this answer just describes how to get a particular literal value into the pipe. The pipe is then free to do whatever it wants with that value, including performing an additional round of processing for special characters. Can this be put into official documentation.

A pipe is a custom Docker image for a container, which contains a script to perform a task. A Dockerfile, which tells us how to build the Docker container that runs your script. These files are stored in a single place, usually a pipe repository. By making a pipe you simplify the configuration of pipelines, and make re-use easy and efficient.

The possibilities for pipes are endless, but already there are pipes to:. Depending on what you need it for, you can make a simple pipe or a complete pipe. They work in the same way, the only difference is how much detail and configuration you add.

In this guide, we'll make a simple pipe first, and then show you the steps to make it a complete pipe. If you are skilled in Docker and want to make a pipe only for private use, you can just make your own Docker container containing all the files required. First, we need a place to put your files, so we start by creating a repository. Take some time to review the dialog's contents. We also have 3 example repositories: a simple pipe repositoryand 2 complete pipe repositories for Bash and Python which you can use as a reference, or import if you like.New to Bitbucket Cloud?

Variables are configured as environment variables in the build container. You can access the variables from the bitbucket-pipelines. You can override the default variables by specifying a variable with the same name. Default value is true. Gets set whenever a pipeline runs. The unique identifier for a build. It increments with each build and can be used to create unique artifact names. The absolute path of the directory that the repository is cloned into within the Docker container.

The URL-friendly version of a repository name. For more information, see What is a slug? The tag of a commit that kicked off the build. This value is only available on tags. Zero-based index of the current step in the group, for example: 0, 1, 2, …. The pull request ID Only available on a pull request triggered build. Your SSH origin, for example: git bitbucket. The exit code of a step, can be used in after-script sections. Values can be 0 success or 1 failed. The person who kicked off the build by doing a push, merge etcand for scheduled builds, the uuid of the pipelines user.

You can add, edit, or remove variables at the account, repository, and deployment environment levels. If you use the same name as an existing variable, you can override it. Each deployment environment is independent so you can use the same variable name with different values for each environment.

Variables defined by the shell should not be used. Do not configure a pipeline variable with the name PATH or you might break all the pipeline steps.

With a basic configuration, you can do things like writing scripts to build and deploy your projects and configuring caches to speed up builds. You can also specify different images for each step to manage different dependencies across actions you're performing in your pipeline. A pipeline is made up of a list of steps, and you can define multiple pipelines in the configuration file.

In the following graph, you can see a pipeline configured under the default section. The pipeline configuration file can have multiple sections identified by particular keywords. Alternatively, you can configure your yaml file without using Bitbucket's interface. Language guides. The file must at least contain one pipeline section containing at least one step and one script inside the step.

The default pipeline runs on every push to the repository unless a branch-specific pipeline is defined. The names or expressions in this section are matched against:.

It merges the destination branch into your working branch before it runs. P ull requests from a forked repository don't trigger the pipeline.

If the merge fails, the pipeline stops. Use the advanced options for running services and running tests in parallel. You can also do things such as configuring a manual step and setting a maximum time for each step, configure 2x steps to get 8GB of memory.

To enable the variables, define them under the custom pipeline that you want to enter when you run the pipeline:. The total number of build minutes used by a pipeline will not change if you make the steps parallel, but you'll be able to see the results sooner.

There is a limit of for the total number of steps you can run in a pipeline, regardless of whether they are running in parallel or serial.
