From c11a77f11d6b454b5490d11a1ad9324b98776151 Mon Sep 17 00:00:00 2001 From: Victor Rubezhny Date: Mon, 13 Jul 2026 00:13:05 +0200 Subject: [PATCH] Add image build support for component deployment Enables the deploy command to build container images as part of the deployment flow. Uses podman, docker, or buildah in the OpenShift terminal so users can interact with registry auth prompts. Key changes: - ContainerRuntimeDetector: Detects available runtime (podman > docker > buildah) - ApplyCommandExecutor: Builds image components in terminal instead of skipping - Unit tests: ContainerRuntimeDetector, image build logic, manifest URI handling, deploy state loading - Integration tests: Runtime detection, deploy/undeploy with inlined resources, local image build without registry Signed-off-by: Victor Rubezhny Assisted-By: Claude Opus 4.6 --- src/devfile/applyCommand.ts | 58 +++++- src/util/containerRuntime.ts | 128 +++++++++++++ test/integration/command.test.ts | 238 +++++++++++++++++++++++- test/unit/devfile/applyCommand.test.ts | 111 +++++++++++ test/unit/devfile/undeploy.test.ts | 60 ++++-- test/unit/util/containerRuntime.test.ts | 199 ++++++++++++++++++++ 6 files changed, 771 insertions(+), 23 deletions(-) create mode 100644 src/util/containerRuntime.ts create mode 100644 test/unit/util/containerRuntime.test.ts diff --git a/src/devfile/applyCommand.ts b/src/devfile/applyCommand.ts index 3d5604a9f..e023dd8bd 100644 --- a/src/devfile/applyCommand.ts +++ b/src/devfile/applyCommand.ts @@ -7,10 +7,13 @@ import * as fs from 'fs/promises'; import * as yaml from 'js-yaml'; import * as path from 'path'; import { window } from 'vscode'; +import { CommandText } from '../base/command'; import { DownloadUtil } from '../downloadUtil/download'; import { Oc } from '../oc/ocWrapper'; import { Apply, DeployedResource } from '../odo/componentTypeDescription'; import { ComponentWorkspaceFolder } from '../odo/workspace'; +import { ContainerRuntimeDetector } from '../util/containerRuntime'; +import { OpenShiftTerminalManager } from '../webview/openshift-terminal/openShiftTerminal'; import { VariableResolver } from './variableResolver'; export class ApplyCommandExecutor { @@ -51,10 +54,11 @@ export class ApplyCommandExecutor { ); } if ((component as any).image) { - // Image build component - skip for now (requires podman/docker/buildah) - // TODO: Implement image building in future PR - // Silently skip image builds - they require container runtime integration - return []; // No resources deployed for image builds + return await this.buildImageComponent( + (component as any).image, + path.dirname(devfilePath), + componentFolder, + ); } throw new Error( `Component '${resolvedApply.component}' is not a kubernetes, openshift, or image component`, @@ -139,6 +143,52 @@ export class ApplyCommandExecutor { } } + private static async buildImageComponent( + imageComponent: any, + devfileDir: string, + componentFolder: ComponentWorkspaceFolder, + ): Promise { + const runtime = await ContainerRuntimeDetector.detectBuildRuntime(); + if (!runtime) { + throw new Error( + 'No container runtime found.
