Chapter 3. Installing Ansible development tools
Red Hat provides two options for installing Ansible development tools.
- Installation on a RHEL container running inside VS Code. You can install this option on MacOS, Windows, and Linux systems.
- Installation on your local RHEL system using an RPM (Red Hat Package Manager) package.
3.1. Requirements
To install and use Ansible development tools, you must meet the following requirements. Extra requirements for Windows installations and containerized installations are indicated in the procedures.
- Python 3.10 or later.
- VS Code (Visual Studio Code) with the Ansible extension added. See Installing VS Code.
- For containerized installations, the Micorsoft Dev Containers VS Code extension. See Installing and configuring the Dev Containers extension.
A containerization platform, for example Podman, Podman Desktop, Docker, or Docker Desktop.
NoteThe installation procedure for Ansible development tools on Windows covers the use of Podman Desktop only. See Installing Podman Desktop on a Windows machine.
-
You have a Red Hat account and you can log in to the Red Hat container registry at
registry.redhat.io
. For information about logging in toregistry.redhat.io
, see Authenticating with the Red Hat container registry.
3.1.1. Requirements for Ansible development tools on Windows
If you are installing Ansible development tools on a container in VS Code on Windows, there are extra requirements:
- Windows Subsystem for Linux(WSL2)
- Podman Desktop
3.1.1.1. Installing WSL
Install WSL2 without a distribution:
$ `wsl --install --no-distribution`
Use
cgroupsv2
by disablingcgroupsv1
for WSL2:Edit the
%USERPROFILE%/wsl.conf
file and add the following lines to forcecgroupv2
usage:[wsl2] kernelCommandLine = cgroup_no_v1="all"
3.1.1.2. Installing Podman Desktop on a Windows machine
Install Podman Desktop. Follow the instructions in Installing Podman Desktop and Podman on Windows in the Podman Desktop documentation.
You do not need to change the default settings in the set-up wizard.
Ensure the podman machine is using
cgroupsv2
:$ podman info | findstr cgroup
Test Podman Desktop:
$ podman run hello
3.1.1.3. Configuring settings for Podman Desktop
Add a
%USERPROFILE%\bin\docker.bat
file with the following content:@echo off podman %*
This avoids having to install Docker as required by the VS Code
Dev Container
extension.Add the
%USERPROFILE%\bin
directory to thePATH
.- Select Settings and search for "Edit environment variables for your account" to display all of the user environment variables.
- Highlight "Path" in the top user variables box, click and add the path.
- Click to set the path for any new console that you open.
3.1.2. Authenticating with the Red Hat container registry
All container images available through the Red Hat container catalog are hosted on an image registry, registry.redhat.io
. The registry requires authentication for access to images.
To use the registry.redhat.io
registry, you must have a Red Hat login. This is the same account that you use to log in to the Red Hat Customer Portal (access.redhat.com) and manage your Red Hat subscriptions.
If you are planning to install the Ansible development tools on a container inside VS Code, you must log in to registry.redhat.io
before launching VS Code so that VS Code can pull the devtools
container from registry.redhat.io
.
If you are running Ansible development tools on a container inside VS Code and you want to pull execution environments or the devcontainer
to use as an execution environment, you must log in from a terminal prompt within the devcontainer
from a terminal inside VS Code.
You can use the podman login
or docker login
commands with your credentials to access content on the registry.
- Podman
$ podman login registry.redhat.io Username: my__redhat_username Password: ***********
- Docker
$ docker login registry.redhat.io Username: my__redhat_username Password: ***********
For more information about Red Hat container registry authentication, see Red Hat Container Registry Authentication on the Red Hat customer portal.
3.1.3. Installing VS Code
- To install VS Code, follow the instructions on the Download Visual Studio Code page in the Visual Studio Code documentation.
3.1.4. Installing the VS Code Ansible extension
The Ansible extension adds language support for Ansible to VS Code. It incorporates Ansible development tools to facilitate creating and running automation content.
For a full description of the Ansible extension, see the Visual Studio Code Marketplace.
See Learning path - Getting Started with the Ansible VS Code Extension for tutorials on working with the extension.
To install the Ansible VS Code extension:
- Open VS Code.
-
Click the Extensions (
) icon in the Activity Bar, or click
, to display the Extensions view. -
In the search field in the Extensions view, type
Ansible Red Hat
. - Select the Ansible extension and click .
When the language for a file is recognized as Ansible, the Ansible extension provides features such as auto-completion, hover, diagnostics, and goto. The language identified for a file is displayed in the Status bar at the bottom of the VS Code window.
The following files are assigned the Ansible language:
-
YAML files in a
/playbooks
directory -
Files with the following double extension:
.ansible.yml
or.ansible.yaml
-
Certain YAML names recognized by Ansible, for example
site.yml
orsite.yaml
-
YAML files whose filename contains "playbook":
playbook.yml
orplaybook.yaml
If the extension does not identify the language for your playbook files as Ansible, follow the procedure in Associating the Ansible language to YAML files.
3.1.5. Configuring Ansible extension settings
The Ansible extension supports multiple configuration options.
You can configure the settings for the extension on a user level, on a workspace level, or for a particular directory. User-based settings are applied globally for any instance of VS Code that is opened. Workspace settings are stored within your workspace and only apply when the current workspace is opened.
It is useful to configure settings for your workspace for the following reasons:
- If you define and maintain configurations specific to your playbook project, you can customize your Ansible development environment for individual projects without altering your preferred setup for other work. You can have different settings for a Python project, an Ansible project, and a C++ project, each optimized for the respective stack without the need to manually reconfigure settings each time you switch projects.
- If you include workspace settings when setting up version control for a project you want to share with your team, everyone uses the same configuration for that project.
Procedure
Open the Ansible extension settings:
- Click the 'Extensions' icon in the activity bar.
Select the Ansible extension, and click the 'gear' icon and then Extension Settings to display the extension settings.
Alternatively, click
to open the Settings page. -
Enter
Ansible
in the search bar to display the settings for the extension.
- Select the Workspace tab to configure your settings for the current VS Code workspace.
The Ansible extension settings are pre-populated. Modify the settings to suit your requirements:
-
Check the
box to enable ansible-lint. -
Check the
Ansible Execution Environment: Enabled
box to use an execution environment. - Specify the execution environment image you want to use in the Ansible > Execution Environment: image field.
- To use Red Hat Ansible Lightspeed, check the Ansible > Lightspeed: Enabled box, and enter the URL for Lightspeed.
-
Check the
The settings are documented on the Ansible VS Code Extension by Red Hat page in the VisualStudio marketplace documentation.
3.1.6. Associating the Ansible language to YAML files
The Ansible VS Code extension works only when the language associated with a file is set to Ansible. The extension provides features that help create Ansible playbooks, such as auto-completion, hover, and diagnostics.
The Ansible VS Code extension automatically associates the Ansible language with some files. The procedures below describe how to set the language for files that are not recognized as Ansible files.
Manually associating the Ansible language to YAML files
The following procedure describes how to manually assign the Ansible language to a YAML file that is open in VS Code.
- Open or create a YAML file in VS Code.
- Hover the cursor over the language identified in the status bar at the bottom of the VS Code window to open the Select Language Mode list.
Select Ansible in the list.
The language shown in the status bar at the bottom of the VS Code window for the file is changed to Ansible.
Adding persistent file association for the Ansible language to settings.json
Alternatively, you can add file association for the Ansible language in your settings.json
file.
Open the
settings.json
file:-
Click
to open the command palette. -
Enter
Workspace settings
in the search box and select Open Workspace Settings (JSON).
-
Click
Add the following code to
settings.json
.{ ... "files.associations": { "*plays.yml": "ansible", "*init.yml": "yaml", } }
3.1.7. Installing and configuring the Dev Containers
extension
If you are installing the containerized version of Ansible development tools, you must install the Microsoft Dev Containers extension in VS Code.
- Open VS Code.
-
Click the Extensions (
) icon in the Activity Bar, or click
, to display the Extensions view. -
In the search field in the Extensions view, type
Dev Containers
. - Select the Dev Containers extension from Microsoft and click .
If you are using Podman or Podman Desktop as your containerization platform, you must modify the default settings in the Dev Containers
extension.
Replace docker with podman in the
Dev Containers
extension settings:- In VS Code, open the settings editor.
Search for
@ext:ms-vscode-remote.remote-containers
.Alternatively, click the Extensions icon in the activity bar and click the gear icon for the
Dev Containers
extension.
-
Set
Dev > Containers:Docker Path
topodman
. -
Set
Dev > Containers:Docker Compose Path
topodman-compose
.
3.2. Installing Ansible development tools on a container inside VS Code
The Dev Containers VS Code extension requires a .devcontainer
file to store settings for your dev containers. You must create a config file for your dev container and reopen your directory in a container in VS Code.
Prerequisites
- You have installed a containerization platform, for example Podman, Podman Desktop, Docker, or Docker Desktop.
-
You have a Red Hat login and you have logged in to the Red Hat registry at
registry.redhat.io
. For information about logging in toregistry.redhat.io
, see Authenticating with the Red Hat container registry. - You have installed VS Code.
- You have installed the Ansible extension in VS Code.
- You have installed the Microsoft Dev Containers extension in VS Code.
If you are installing Ansible development tools on Windows, launch VS Code and connect to the WSL machine:
-
Click the
Remote
( ) icon. - In the dropdown menu that appears, select the option to connect to the WSL machine.
-
Click the
Procedure
- In VS Code, open the directory where you want to store the configuration files for your development container.
-
Create a subdirectory called
.devcontainer
. In the
.devcontainer
directory, create a file calleddevcontainer.json
.You must use different settings depending on whether you are using Podman or Docker.
If you are using Podman or Podman desktop, add the following text to
devcontainer.json
:{ "name": "ansible-dev-container-podman", "image": "registry.redhat.io/ansible-automation-platform-25/ansible-dev-tools-rhel8:latest", "containerUser": "root", "runArgs": [ "--cap-add=CAP_MKNOD", "--cap-add=NET_ADMIN", "--cap-add=SYS_ADMIN", "--cap-add=SYS_RESOURCE", "--device", "/dev/fuse", "--security-opt", "seccomp=unconfined", "--security-opt", "label=disable", "--security-opt", "apparmor=unconfined", "--security-opt", "unmask=/sys/fs/cgroup", "--userns=host", "--hostname=ansible-dev-container" ], "customizations": { "vscode": { "extensions": ["redhat.ansible"] } } }
If you are using Docker or Docker desktop, add the following text to
devcontainer.json
:{ "name": "ansible-dev-container-docker", "image": "registry.redhat.io/ansible-automation-platform-25/ansible-dev-tools-rhel8:latest", "containerUser": "root", "runArgs": [ "--privileged", "--device", "/dev/fuse", "--hostname=ansible-dev-container" ], "updateRemoteUserUID": true, "customizations": { "vscode": { "extensions": ["redhat.ansible"] } } }
Reopen the directory in a container.
If VS Code detects that your directory contains the
devcontainer.json
file, the following notification appears:Click Reopen in Container.
-
If the notification does not appear, click the
Remote
( ) icon. In the dropdown menu that appears, select Reopen in Container.
The Remote () status in the VS Code Status bar displays opening Remote
and a notification indicates the progress in opening the container.
Verification
When the directory reopens in a container, the Remote () status displays Dev Container: ansible-dev-container
.
The base image for the container is a Universal Base Image Minimal (UBI Minimal) image that uses microdnf
as a package manager. The dnf
and yum
package managers are not available in the container.
For information about using microdnf
in containers based on UBI Minimal images, see Adding software in a minimal UBI container in the Red Hat Enterprise Linux Building, running, and managing containers guide.
3.3. Installing Ansible development tools from a package on RHEL
