Concerns: No actual build from source is performed; the image copies a prebuilt Kong binary from the repository instead of compiling Kong from source., The builder stage installs packages that are not used in the final runtime image, which is wasteful., Reliance on bin/kong and the generated /etc/kong/kong.yaml may fail if these paths are missing in the repo or at build time.

Status - VerifyBuild status: build_failed Concerns (CI/build reliability and artifacts) - Build relies on Bazel/Bazelisk in the builder stage; ensure network access and that Bazel-related steps complete reliably in CI. If bazel/bazelisk installation fails, the build could break. - COPY . . and build context: copying the entire repo may pull in large files or sensitive data; consider narrowing the context or adding a .dockerignore. - The runtime binary path /kong/bazel-bin/build/kong-dev/kong is brittle; if the Bazel output layout changes, the COPY could break. Consider documenting or validating the path or building a more robust artifact location. - kong version is executed at image build time to verify the binary; if runtime deps aren’t fully present in the runtime stage, this could fail and block image build. This check might be better placed in a separate runtime smoke test rather than during build. - No HEALTHCHECK or explicit port exposure; consider adding HEALTHCHECK and, if this is meant to run a service, exposing the proper port and startup checks. Build error - Failing step: RUN make build-kong - Context: builder 9/9 in Dockerfile, invoked to build Kong from source - Related make target: build-kong (Makefile:95) Exact error messages (selected) - Error in patch: Unable to load package for //build:patches/01-revert-LD-environment.patch: BUILD file not found in any of the following directories. Add a BUILD file to a directory to mark it as a package. - Error computing the main repository mapping: no such package '@@rules_foreign_cc//foreign_cc': Unable to load package for //build:patches/01-revert-LD-environment.patch: BUILD file not found in any of the following directories. Add a BUILD file to a directory to mark it as a package. - make: *** [Makefile:95: build-kong] Error 1 - Dockerfile:28 - failed to solve: process "/bin/sh -c make build-kong" did not complete successfully: exit code: 2 Failing command/step - Failing step: RUN make build-kong - Context: builder 9/9 in Dockerfile, invoked to build Kong from source - Related make target: build-kong (Makefile:95) Missing packages/files mentioned - BUILD file not found in /kong/build (BUILD file not found in any of the following directories) - Patch file missing: patches/01-revert-LD-environment.patch is not loadable (referenced as //build:patches/01-revert-LD-environment.patch) - As a consequence, repository mapping for @@rules_foreign_cc//foreign_cc could not be resolved Version information related to the failure - Bazel bootstrap attempted: Downloading https://releases.bazel.build/7.3.1/release/bazel-7.3.1-linux-x86_64... - Bazel installation started and local Bazel server connected - The failure is due to a patch/build file issue during repository fetch (not a Bazel version mismatch, but Bazel 7.3.1 was used for the build).

Summary: - Failing step/command - Builder step [builder 8/8]: RUN if [ -x bin/kong ]; then echo "Using prebuilt Kong binary from repo"; else echo "Building Kong from source"; make build-kong; fi - In this step, the inner command make build-kong fails (curl invoked during the build). - Exact error messages and exit codes - curl: (23) Failure writing output to destination - Makefile:60: bin/bazel] Error 23 - Overall RUN exit code: 2 - Missing packages or files mentioned - None explicit. The error is curl failing to write to its destination; no missing file/package messages are shown. - Version mismatch information - None explicitly mentioned. The log shows prior steps referencing Bazelisk (v1.10.1) installation, but no version mismatch errors are reported.

Concerns: The Dockerfile does not build from source; it relies solely on a prebuilt binary in the repo (copy of /kong/bin/kong). If the prebuilt binary is absent, the final image build will fail at the COPY step., COPY --from=builder /kong/bin/kong /usr/local/bin/kong will fail during build if /kong/bin/kong does not exist in the builder stage, making the image fragile., There is no actual build process (no compile or install steps to produce Kong from source); this contradicts the expectation of building an application from source for a Lua-based web service.

Concerns: The Dockerfile does not build from source; it only checks for a prebuilt Kong binary and may skip any build steps entirely., COPY --from=builder /kong/bin/kong /usr/local/bin/kong will fail at build time if the Kong binary does not exist in the repository's builder stage., The runtime stage assumes the Kong binary exists; in repos without a prebuilt binary, the image build will fail, making the image brittle.

Summary of Docker build error
Exact error message and exit code
- E: Unable to locate package openresty
- Exit code: 100
Failing command/step
- Dockerfile step (builder 3/7):
RUN curl -fsSL https://openresty.org/package/pubkey.gpg | apt-key add - \
&& add-apt-repository -y "deb http://openresty.org/package/ubuntu $(lsb_release -sc) openresty" \
&& apt-get update \
&& apt-get install -y --no-install-recommends openresty
- Context: This is the step attempting to install OpenResty from the OpenResty APT repo during the Kong build.
Missing packages or files mentioned
- openresty: The package could not be located/installed.
- Related repository message:
- W: Skipping acquire of configured file 'openresty/binary-amd64/Packages' as repository 'http://openresty.org/package/ubuntu jammy InRelease' doesn't have the component 'openresty' (component misspelt in sources.list?)
Version mismatch / repository issue
- The OpenResty APT repo for Ubuntu Jammy (22.04) is added, but it does not provide the expected 'openresty' component, causing apt to fail with "Unable to locate package openresty." This indicates a mismatch or misconfiguration between the repository entry and the distro, i.e., the repo (jammy InRelease) lacks the required openresty component.# syntax=docker/dockerfile:1 FROM ubuntu:22.04 AS builder ENV DEBIAN_FRONTEND=noninteractive # Install essential build-time tools and dependencies RUN apt-get update && apt-get install -y --no-install-recommends \ ca-certificates curl git unzip build-essential pkg-config zlib1g-dev \ libpcre3-dev libyaml-dev libssl-dev golang-go luarocks \ && rm -rf /var/lib/apt/lists/* WORKDIR /kong # Copy the repository into the image COPY . . # Build Kong from source using the project's Bazel/Makefile workflow RUN make build-kong FROM ubuntu:22.04 AS runtime ENV DEBIAN_FRONTEND=noninteractive # Runtime dependencies (minimal) RUN apt-get update && apt-get install -y --no-install-recommends \ ca-certificates libyaml-0-2 openssl curl zlib1g libpcre3 \ && rm -rf /var/lib/apt/lists/* # Copy the built Kong binary from the builder stage COPY --from=builder /kong/bazel-bin/build/kong-dev/kong /usr/local/bin/kong # Verify binary is functional RUN kong version # Default command to show version; suitable for smoke tests ENTRYPOINT ["/usr/local/bin/kong"] CMD ["version"]
Concerns: Missing Bazel or equivalent build tool in builder stage; 'make build-kong' typically requires Bazel and it is not installed in the Dockerfile, The build output path '/kong/bazel-bin/build/kong-dev/kong' may not exist depending on the build configuration; COPY --from=builder may fail if the path differs, No runtime smoke test verifying server startup or HTTP endpoints; smoke test only checks version output

Concerns: Does not build from source; uses a prebuilt Kong binary copied from the repository instead of compiling from source, No explicit build steps to compile from source in the Dockerfile; may undermine reproducibility and licensing checks, Potential runtime/library dependencies are installed, but the builder stage does not install build-time tools, which could mask missing dependencies during the actual build

Concerns: COPY --from=builder /kong-dist/kong /usr/local/bin/kong will fail if the Kong binary isn't built (missing artifacts on first build)., Best-effort copying section uses glob and conditional copies; this is brittle and can break builds if bazel outputs different paths., No robust verification for missing artifacts (no VerifyBuild step); the runtime stage assumes /kong-dist/kong exists, which may not be the case if the build didn't produce artifacts.

Concerns: Invalid COPY syntax in the first stage: uses --from=0 inside the same stage and includes shell redirection (2>/dev/null || true), which is not valid Dockerfile syntax., Stage 0 attempts to copy from another stage (or itself) in a way that will fail to produce /kong-dist/kong; the final COPY in stage 1 depends on this but will likely fail if the binary isn't produced., There is no actual build from source; the Dockerfile relies on prebuilt binaries that may not exist in the repo, making the image effectively incomplete or placeholder., If the prebuilt binaries are not present, the final image will be missing /usr/local/bin/kong and /usr/local/bin/kong-health, causing the CMD to fail at runtime., The final CMD starts Kong in the foreground with a DB-less config, but without guaranteeing the binary exists, the container may crash on start.

Concerns: No build from source: the image uses prebuilt Kong binaries copied from bin/; there is no build step in the Dockerfile, COPY instructions assume prebuilt binaries exist in the build context (bin/kong and bin/kong-health) without verification, No explicit healthcheck or runtime verification beyond the binary; potential lack of runtime dependencies on Ubuntu 22.04, No version pinning or checksum validation for the copied binaries; potential supply chain risk, DB-less config is created via printf in a RUN; if the file needs special permissions or encoding, this could be brittle, No explicit USER directive; container runs as root by default

Here's a concise summary of the Docker build error with the requested details preserved.
- Exact error message and exit code
- curl: (23) Failure writing output to destination
- make: *** [Makefile:60: bin/bazel] Error 23
- Overall exit code: 2 (as shown by the error line: "ERROR: ... exit code: 2")
- Failing command/step
- RUN make build-kong (builder step 5/7)
- Missing packages or files mentioned
- head: cannot open '/etc/ssl/certs/java/cacerts' for reading: No such file or directory
- This occurred during the ca-certificates-java setup and indicates a missing Java CA certificates file.
- Version mismatch info
- No explicit version mismatch information is shown in the log. The build uses Ubuntu 22.04 (jammy) and OpenJDK 11 components; no clear mismatch is reported.# Kong: build-from-source multi-stage Dockerfile

Concerns: No actual build from source: the Dockerfile uses prebuilt binaries copied from the repository instead of compiling/building Kong from source., Reliance on prebuilt binaries: potential mismatch with the base image (Ubuntu 22.04) or missing runtime dependencies may cause runtime failures if the binaries expect different environments., No explicit check for binary compatibility or dependencies: while the final image is simple, there is no validation that the Kong binary will run correctly in this environment., Clarity on kong-health usage: a second binary (kong-health) is copied but not clearly used in the runtime or tests, which could indicate incomplete smoke coverage., Security/upgrade considerations: copying binaries from repo without verification or signing could pose security risks; no version pinning or checksum validation shown.
