Atomist software delivery machine (SDM) extension Pack for an Atomist SDM to integrate docker.

See the Atomist documentation for more information on what SDMs are and what they can do for you using the Atomist API for software.

Usage

Docker Image Creation

TODO

Dockerfile Parsing and Manipulation

This module includes support for parsing Docker files, within the Atomist tree path model. This allows us to query instructions in Docker files and update them without otherwise changing file content or formatting.

The following example returns the image name:

const images: string[] = await astUtils.findValues(p, DockerFileParser, "Dockerfile",
     "//FROM/image/name");

The following example uses DockerFileParser exported by this package, to update an image tag of argon, from node:argon to xenon to produce a file referencing node:xenon.

await astUtils.doWithAllMatches(p, DockerFileParser, "Dockerfile",
    "//FROM/image/tag",
    n => n.$value = "xenon");

This example uses a custom function to find all RUN instructions that invoke rm:

const runs = await astUtils.findValues(p, DockerFileParser, "Dockerfile",
    "//RUN[?removes]",
    {
        removes: n => n.$value.includes("rm "),
    });

We introduce the pair level to handle LABELs. For example, consider the following input:

LABEL "com.example.vendor"="ACME Incorporated"

The following code queries it:

const labelKeys = await astUtils.findValues(p, DockerFileParser, "Dockerfile",
            "//LABEL/pair/key");
assert.strictEqual(labelKeys[0], `com.example.vendor`);
const labelValues = await astUtils.findValues(p, DockerFileParser, "Dockerfile",
    "//LABEL/pair/value");
assert.strictEqual(labelValues[0], `ACME Incorporated`);
const knownKeys = await astUtils.findValues(p, DockerFileParser, "Dockerfile",
    "//LABEL/pair[/key[@value='com.example.vendor']]/value");
assert.strictEqual(knownKeys[0], `ACME Incorporated`);

Please see dockerFileParser.test.ts for further examples.
