Additional User-Agent request headers can be added by setting the user_agent_headers option.
When you want to identify a product using mixlib-install as a dependency we recommend the format product/version.
options = {
channel: :stable,
product_name: 'chef',
user_agent_headers: ["my_product/1.2.3", "somethingelse"],
}Collecting software dependencies and license content for ArtifactInfo instances
requires additional requests to the repository server. By default, collection is disabled.
To return data for instance methods software_dependencies and license_content, the include_metadata option must be enabled.
options = {
channel: :current,
product_name: 'chef',
product_version: :latest,
platform: 'mac_os_x',
platform_version: '10.15',
architecture: 'x86_64',
include_metadata: true,
}
artifact = Mixlib::Install.new(options).artifact_info
artifact.license_content.class
# => String
artifact.software_dependencies.class
# => Hash
# By default, the instance methods return nilmixlib-install generates the bootstrap installation scripts known as install.sh and install.ps1. The associated install script will be returned when calling #install_command on the Mixlib::Install instance.
Mixlib::Install instantiation option install_command_options can accept variables (bourne) or parameters (powershell) to modify the behavior of the install scripts.
Some of the more common options include:
download_url_override: Use the provided URL instead of fetching the metadata URL from Chef Software Inc's software distribution systems.
checksum: SHA256 value associated to the directed file for the download_url_override option. This setting is optional. Not setting this will download the file even if a cached file is detected.
install_strategy: Set to "once" to have the script exit if the product being installed is detected.
options = {
product_name: 'chef',
install_command_options: {
download_url_override: "https://file/path",
checksum: "OPTIONAL",
install_strategy: "once",
}
}
Mixlib::Install.new(options).install_commandThe API uses Ruby's OpenURI module to load proxy environment variables (http_proxy, https_proxy, ftp_proxy, no_proxy).
When install.sh and install.ps1 are executed as standalone scripts the will rely on environment variables to configure proxy settings. The install scripts will not configure proxy settings by default.
In order to customize the proxy environment variables for generated install scripts they must be set by the install_command_options option. Setting these options will override session environment variables.
Bourne install script (install.sh) supports http_proxy, https_proxy, ftp_proxy, and no_proxy passed as keys to install_command_options.
Powershell install script (install.ps1) supports http_proxy passed as a key to install_command_options.
Create a ruby file in your application and use the product DSL like this (see product.rb for available properties):
product "cinc" do
product_name "Cinc Infra Client"
package_name "cinc-client"
api_url "https://packages.cinc.sh"
end
Then set an environment variable to load them like this on linux:
export EXTRA_PRODUCTS_FILE=/path/to/your/file.rb
Calls to mixlib-install now allow to target your new product, assuming the api_url match pacakges api for /<channel>/<product>/versions and /<channel>/<product>/<version>/artifacts endpoints.
VCR is a tool that helps cache and replay http responses. When these responses change or when you add more tests you might need to update cached responses. Check out spec_helper.rb for instructions on how to do this.
