Run shell script in yaml

Comment 0. YAML builds have many advantages over traditional build definitions, especially because YAML build definitions follows branching of code, a killer feature that is fantastic if you use GitFlow. YAML build definitions are stored in code, this allows them to follow branches, minimizing the need to maintain builds that should build code in a different moment in time. As an example, I have a build where I have tasks to publish some web sites.

If I had a new web site to publish, I could add another task in the YAML build, but the build still works for older branches, especially for the master branch that represents my code in production. To minimize the impact, I tend to use PowerShell scripts stored inside the code repository to perform build tasks. This was an old trick useful when YAML build was not present. Scripts allows you to create a generic build, add some tasks to run PowerShell scripts, and the result is that scripts follow branches.

As you can see from Figure 1, PowerShell tasks are not converted as a task, but with a node of type PowerShell, followed by parameters. This is perfectly valid because a YAML build can contain a PowerShell node, but in my specific situation, the build failed because the conversion failed to set up a working directory.

This is the declaration of the task:. As usual, you specify a task and the type — in this example, PowerShell 2.

It is important to have the version after the character — it should be equal to the version of the task in the standard build, as shown in Figure 2. To figure out the input parameter name of the tasks e. Figure 3: Tasks inside the working folder of an agent. Inside the folder of the chosen task, there are all the latest versions for any major version, and inside each version folder, there is a task. See the original article here.

Introduction Pipeline configuration begins with jobs. Jobs are the most fundamental element of a.

Jobs are: Defined with constraints stating under what conditions they should be executed. Top-level elements with an arbitrary name and must contain at least the script clause. Not limited in how many can be defined. Of course a command can execute code directly. Jobs are picked up by Runners and executed within the environment of the Runner.

What is important, is that each job is run independently from each other. Validate the. Change them to a different form. The following table lists available parameters for jobs: Keyword Description script Shell script which is executed by Runner. Also available: image:name and image:entrypoint. Also available: services:nameservices:aliasservices:entrypointand services:command. Also available: only:refsonly:kubernetesonly:variablesand only:changes.

Note: Parameters types and type are deprecated. Setting default parameters Some parameters can be set globally as the default for all jobs using the default: keyword. Default parameters can then be overridden by job-specific configuration. You can disable inheritance of globally defined defaults and variables with the inherit: parameter.

To enable or disable the inheritance of all variables: or default: parameters, use the following format: default: true or default: false variables: true or variables: false To inherit only a subset of default: parameters or variables:specify what you wish to inherit, and any not listed will not be inherited. For example: job : script : " bundle exec rspec" YAML anchors for scripts are available.

This parameter can also contain several commands using an array: job : script : - uname -a - bundle exec rspec Note: Sometimes, script commands will need to be wrapped in single or double quotes.Hi, This is great, but is it intended to work only with indentations made of two spaces?

Customizing the Build

Our yaml files use four spaces indentations and it doesn't work with them. Pardon me for pointing this out, droath, but arrays and array2 are hashes. Only array1 and array3 are proper arrays. FlipMartin if you are using 4 spaces the variables will get two underscores as delimiter, e. Hope your ok with it.

I was unsuccessful with using your approach. And unfortunately I am not able to introduce other tooling like python packages such as niet into my project.

You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using Minikubeor you can use one of these Kubernetes playgrounds:. In this exercise, you create a Pod that has one Container. The Container runs the nginx image. Here is the configuration file for the Pod:. Look again at the configuration file for your Pod. In your shell, create an index. In an ordinary command window, not your shell, list the environment variables in the running Container:.

If a Pod has more than one Container, use --container or -c to specify a Container in the kubectl exec command. For example, suppose you have a Pod named my-pod, and the Pod has two containers named main-app and helper-app. The following command would open a shell to the main-app Container.

Yes No.So I followed the kubernetes documentation to execute a command using a yaml file:. The portion in args is where the actual commands are passed to the shell. You use semicolon to separate the commands. OR an easier wary in my opinion is to build your own dockerfile. Use RUN to execute your commands.

This should help. Try something like this:.
