Class Method Summary

• .all_workload_resources(yml : Array(YAML::Any), default_namespace : String = "default") : Array(YAML::Any)
• .chart_name(helm_chart_repo) : String
• .ensure_resource_with_namespace(resource : YAML::Any, default_namespace : String) : YAML::Any
• .generate_manifest(release_name : String, namespace : String) : String
• .helm_gives_k8s_warning? : Tuple(Bool, String | Nil)
• .helm_repo_add(helm_repo_name, helm_repo_url) : Bool
• .install(release_name : String, helm_chart : String, namespace : String | Nil = nil, create_namespace = false, values = nil) : CMDResult

  the way values currently work is they are combined with the chart (e.g.

• .kind_exists?(args, config, kind, default_namespace : String = "default") : Bool
• .pull(helm_repo_name, helm_chart_name, version = nil, destination = nil, untar = true) : CMDResult
• .pull_oci(oci_address, version = nil, destination = nil, untar = true) : CMDResult

  This method could be overloaded but there is a trap - if calling this method without all args provided, to make use of default values for them, both method could be easily matched.

• .template(release_name, helm_chart_or_directory, output_file : String = "cnfs/temp_template.yml", namespace : String | Nil = nil, values : String | Nil = nil) : CMDResult
• .uninstall(release_name, namespace = nil) : CMDResult
• .workload_resource_by_kind(ymls : Array(YAML::Any), kind : String) : Array(YAML::Any)
• .workload_resource_kind_names(resources : Array(YAML::Any), default_namespace : String = "default") : Array(NamedTuple(kind: String, name: String, namespace: String))
