feat: self-contained container image build #514
Conversation
WalkthroughThe changes update the CI/CD workflow, build automation, Dockerfile, and packaging script. The GitHub Actions workflow now extracts and exports versioning details, removes legacy binary steps, and adds a secure image build job based on tag conditions. The Makefile introduces new variables and targets for Docker Buildx setup and image publishing workflows. The Dockerfile is refactored with a multi-stage build that compiles the application in a builder stage and then prepares the final image. The packaging script now has clearer variable naming and logic to select the build command and assign image tags. Changes

Approval: Comprehensive Package Setup Verified
The package installation and repository setup have been confirmed. Our preliminary security check script listed the installed packages (with some extraneous tokens from the extraction method), and no known vulnerabilities were immediately apparent for the intended packages. A manual review of the extracted package list (focusing on the actual packages installed such as fuse, libaio-devel, libibverbs, librdmacm1, librdmacm-utils, perl-Config-General, sg3_utils, qemu-tools, etc.) is still advised to be thorough.

14-19: Review of Build Job Outputs DeclarationThe new outputs are declared correctly and reference the values from the
build_infostep. Verify that all downstream jobs are updated to use these outputs.
24-31: Review of Build Info Declaration StepThe
build_infostep initializes the required variables before they’re populated. The default empty-string initializations are acceptable, though you may want to add comments if future maintainers might question why defaults are set.
48-54: Review of Version Info Echo BlockThe block echoing the version info to
$GITHUB_OUTPUTand printing it via a heredoc is clear. Just ensure that this version information is not sensitive. Otherwise, the implementation is straightforward.
66-84: Review of Community Image Build and Push StepThe configuration for building and publishing the community image is consistent with the new outputs and appears correct. All the required inputs, such as image details and credentials, are properly referenced.
32-41:⚠️ Potential issueCritical Issue: Version Extraction Logic
The version extraction in line 34 uses a regex (
s/^v([0-9.]*)$/\1) that expects the version string to start withv. However, the Git reference (github.ref) typically contains the full string (e.g.,refs/tags/v1.2.3), so this regex will not match correctly. Please update the command to extract the version correctly. For example:- version=$(sed -E 's/^v([0-9.]*)$/\1' <<<$ref ) + version=$(echo "$ref" | sed -E 's/^refs\/tags\/v([0-9.]+)$/\1/')This change ensures the prefix is properly stripped.
Likely invalid or redundant comment.

32-41:⚠️ Potential issueFix Version Extraction Logic in build_info Step
The current version extraction via sed does not account for the full ref format (refs/tags/v...). This may result in an empty or incorrect version string. Consider revising the command as follows:- version=$(sed -E 's/^v([0-9.]*)$/\1' <<<$ref ) + version=$(echo "$ref" | sed -E 's#^refs/tags/v([0-9.]+)$#\1#')Also, verify that

12-21: 🛠️ Refactor suggestionAdd parameter validation and documentation.
Security-sensitive parameters should be documented and validated to prevent misuse.
Add parameter validation and documentation:
+# Configuration parameters: +# REPO: Container registry repository (default: longhornio) +# IMAGE_NAME: Name of the container image (default: project name) +# TAG: Image tag (default: auto-generated from version) +# OUTPUT_ARGS: Docker buildx output arguments (default: --load) +# IS_SECURE: Enable security features like SBOM and attestation (default: false) +# MACHINE: Builder instance name (default: '') +# TARGET_PLATFORMS: Target build platforms (default: '') +# IID_FILE: Image ID file path (default: '') +# IID_FILE_FLAG: Custom image ID file flag (default: '') +# Validate security parameters +if [[ "$IS_SECURE" != "true" && "$IS_SECURE" != "false" ]]; then + echo "Error: IS_SECURE must be 'true' or 'false'" >&2 + exit 1 +fi✅ Verification successful
Error: No shell scripts or web queries found
Parameter validation and documentation implemented correctly.
The changes now include clear inline documentation for all configuration parameters (with default values) and a validation check to ensure the security-sensitive parameter
IS_SECUREhas an acceptable value ("true"or"false"). This prevents misuse and improves clarity.
- Documentation comments for parameters have been added.
- A validation block is included for
IS_SECURE.

2-13:⚠️ Potential issueVerify golang image version.
The specified golang version "1.23" seems incorrect as it's not a valid Go version.
✅ Verification successful
🌐 Web query:
What is the latest version of golang?💡 Result:
The latest stable version of Go (Golang) as of February 2025 is **Go 1.23.5**, released on January 16, 2025[2][6]. This minor update includes security fixes for `crypto/x509` and `net/http` packages along with runtime bug fixes[2]. For developers wanting to test upcoming features, **Go 1.24rc2** is available as an unstable release candidate[5]. However, production environments should continue using the stable Go 1.23 series. Key details about recent releases: - **Go 1.23** (major release): Introduced toolchain improvements and library updates while maintaining compatibility[1][3] - **Go 1.22** (previous major version): Last updated to v1.22.11 in January 2025 with security patches[2] - **Installation**: Current stable can be installed via `go get go@1.23.5` or downloaded from official sources[6] The Go team maintains regular release cycles with major versions every 6 months and frequent minor updates addressing security and stability[2][4]. Citations: - 1: https://go.dev/blog/go1.23 - 2: https://go.dev/doc/devel/release - 3: https://tip.golang.org/doc/go1.23 - 4: https://tip.golang.org/doc/go1.22 - 5: https://go.dev/dl/ - 6: https://go.dev/doc/install - 7: https://groups.google.com/g/golang-nuts/c/_ROx_UGCCCg
Verified: Go version in Dockerfile is correct.
- The Dockerfile uses
golang:1.23, which is valid given that Go 1.23 is the current stable series.- The web query confirms that while the latest patch version is Go 1.23.5, specifying the major version "1.23" is acceptable for ensuring the use of the Go 1.23 series.

34-39:⚠️ Potential issueVersion Extraction Logic Improvement
The current version extraction uses:version=$(sed -E 's/^v([0-9.]*)$/\1' <<<$ref )This will likely fail since
$reffrom GitHub is in the formatrefs/tags/vX.Y.Z. Please update the extraction logic to correctly remove the prefix. For example:- version=$(sed -E 's/^v([0-9.]*)$/\1' <<<$ref ) + version=$(echo "$ref" | sed -E 's/^refs\/tags\/v([0-9.]+)$/\1/')This change addresses the known version extraction issues noted in previous reviews.

10-13: Build Script Execution & Secret Handling
The Dockerfile sets the build script (/app/scripts/build) as executable and executes it. Please verify that the build script handles failures gracefully and that it does not inadvertently log or expose any secret information (per the PR objective regarding EIO secrets).
35-36: Binary Retrieval from Builder Stage
The updated COPY command (COPY --from=builder /app/bin/backing-image-manager-${ARCH} /usr/local/bin/backing-image-manager) and the subsequent permission fix (viaRUN chmod +x /usr/local/bin/backing-image-manager) correctly retrieve and prepare the binary for the final image.

14-18: Job Outputs Definition
Defining job-level outputs (version_major,version_minor,version_build, andimage_tag) to propagate build info is clear and aligns with the new versioning requirements.
24-33: Build Info Initialization & Branch Extraction
The newbuild_infostep initializes version variables and extracts the branch name properly (using the fallback withGITHUB_HEAD_REF). One note: verify that${{ github.ref }}expands as expected within the shell session.
44-47: Setting GitHub Action Outputs
Echoing the extracted version details to$GITHUB_OUTPUTis correctly implemented, ensuring downstream steps have access to the required information.
49-55: Logging Extracted Build Info
The multi-line echo (usingcat <<EOF) provides clear logging of build information. Just double-check to ensure that no sensitive data is logged—even though version details are not secret—to align with security best practices.
66-86: Build & Publish Image Job Configuration
Thebuild_push_imagejob, which logs into Docker Hub and then runsmake workflow-image-build-push, is set up correctly. Ensure that the environment variableTAG, sourced from the earlier outputs, propagates as intended and that this job does not expose any secrets in its logs.

What's the purpose of saving the image locally here? For debugging? If yes, suggest making a flag to enable it and disable it by default, since the image will be pushed to the registry instead.

1-47: Consider implementing SLSA Level 3 requirements.While the multi-stage build improves security by isolating the build environment, consider implementing additional SLSA Level 3 requirements mentioned in the PR objectives:
- Hermetic builds
- Reproducible builds
- Provenance generation
Consider:
- Pin all base image versions with SHA digests
- Lock all dependency versions
- Implement build provenance generation using SLSA framework
Let me verify the current base image versioning:
#!/bin/bash # Check if base images use SHA digests rg -i "FROM .+@sha256:" package/Dockerfile

23-29: Improve version handling robustness.Two issues need attention:
- The VERSION variable used in the fallback case is not defined.
- The jq command output should be properly validated.

47-48: LGTM! Good security practices implemented.The secure build configuration with SBOM generation and provenance attestation aligns well with the PR's security focus and SLSA Level 3 requirements.
50-58: Improve command logging to prevent secrets leakage.The current approach of echoing the entire command could leak sensitive information in logs.
-echo "${BUILD_CMD[@]}" "${IMAGE_BUILD_CMD_ARGS[@]}" +"${BUILD_CMD[@]}" "${IMAGE_BUILD_CMD_ARGS[@]}" 2>&1 | grep -v "secret" || truepackage/Dockerfile (2)
6-7: Limit build context exposure.Copying the entire context into the builder stage could expose sensitive files.
Previous review already suggested adding a
.dockerignorefile to minimize the build context and enhance security.
12-13: Enhance secrets handling during build.Given the PR objective to keep EIO secrets confidential, ensure build secrets are properly handled and don't leak into image layers.
Consider using Docker's secret mounting feature:
-RUN /app/scripts/build +RUN --mount=type=secret,id=eio_secrets \ + export EIO_SECRETS_FILE=/run/secrets/eio_secrets && \ + /app/scripts/buildLet me verify if the build script handles secrets:
❌ Verification inconclusive
🏁 Script executed:
#!/bin/bash # Search for secrets handling in build script rg -i "secret|credential|key|token" scripts/buildLength of output: 51
Enhance secret handling in the build process
The search in the build script did not reveal any handling for secrets (using keywords like "secret", "credential", "key", "token"). This confirms that the build script does not currently implement any secret validation or masking. Given the PR objective to protect EIO secrets, the Dockerfile should leverage Docker’s secret mounting (as suggested) to prevent secrets from leaking into image layers.
- The build script (
scripts/build) shows no explicit reference to secrets handling.- The Dockerfile’s RUN command lacks any Docker secrets mount options.
Please consider revising the Dockerfile to use Docker’s secret features as follows:
-RUN /app/scripts/build +RUN --mount=type=secret,id=eio_secrets \ + export EIO_SECRETS_FILE=/run/secrets/eio_secrets && \ + /app/scripts/build
