Implementation Reference
- src/index.ts:1675-1728 (handler)Handler function implementing Docker registry operations: search, login, logout, push, pull, tag. Constructs docker commands based on action and parameters, executes via executeDockerCommand, and returns formatted results or errors.
async ({ action, query, image, tag, newTag, registry, username, password }) => { try { let command: string; switch (action) { case "search": if (!query) throw new Error("Search query is required"); command = `docker search ${query}`; break; case "login": command = `docker login${registry ? ` ${registry}` : ""}`; if (username && password) { command += ` -u ${username} -p ${password}`; } break; case "logout": command = `docker logout${registry ? ` ${registry}` : ""}`; break; case "push": if (!image) throw new Error("Image name is required for push"); command = `docker push ${image}${tag ? `:${tag}` : ""}`; break; case "pull": if (!image) throw new Error("Image name is required for pull"); command = `docker pull ${image}${tag ? `:${tag}` : ""}`; break; case "tag": if (!image || !newTag) throw new Error("Image name and new tag are required for tag action"); command = `docker tag ${image}${tag ? `:${tag}` : ""} ${newTag}`; break; } const result = await executeDockerCommand(command); return { content: [ { type: "text", text: `Registry ${action} completed:\n\n${result.stdout}${result.stderr ? `\nWarnings:\n${result.stderr}` : ""}` } ] }; } catch (error) { return { content: [ { type: "text", text: `Error with registry operation: ${error instanceof Error ? error.message : String(error)}` } ], isError: true }; } } - src/index.ts:1660-1673 (schema)Input schema defining parameters for docker_registry tool: action (enum), query, image, tag, newTag, registry, username, password with Zod validation and descriptions.
