Concerns
- Potential Bazel output path mismatch: the script copies /bazel-bin/java/src/org/openqa/selenium/grid/selenium_server_deploy.jar to /opt/selenium/server.jar, but Bazel's actual output path can vary between targets and Bazel version; this may cause the copy to fail at build time.
- COPY . . copies the entire repository into the image; without a .dockerignore, the build context can be large and slow. Consider adding a dockerignore to exclude build artifacts and tests not needed at build time.
- Dependency on Bazelisk/bazel: the build step relies on bazel being present and properly configured via Bazelisk. If the target //:server changes or Bazel rules require extra tools, the build could fail. The 'RUN bazel --version || true' does not guarantee Bazel is installed before the subsequent build step.
- The final CMD assumes the built server jar is fully self-contained and runnable with 'java -jar'. If the server requires additional resources or classpath setup not included in the jar, startup may fail.
Build error
- Exact error message and exit code:
- curl: (22) The requested URL returned error: 404
- The build failed: process "/bin/sh -c curl -fsSL https://bazel.build/bazelisk-linux-amd64 -o /usr/local/bin/bazel && chmod +x /usr/local/bin/bazel" did not complete successfully: exit code: 22
- Failing command/step:
- Step [ 4/10] RUN curl -fsSL https://bazel.build/bazelisk-linux-amd64 -o /usr/local/bin/bazel && \
chmod +x /usr/local/bin/bazel
- Missing packages or files mentioned:
- 404 on Bazelisk URL indicates the Bazel binary could not be downloaded from https://bazel.build/bazelisk-linux-amd64 (baited file not found)
- Earlier in the log during ca-certificates-java setup:
- head: cannot open '/etc/ssl/certs/java/cacerts' for reading: No such file or directory
- Version mismatch info:
- No explicit version mismatch reported. The failure is due to a 404 on the Bazelisk download URL, not a version conflict.
- The log shows prior installs of Node.js 20.x and OpenJDK 17, but nothing indicating a mismatch that caused the failure.# Base image with stable Debian/Ubuntu userland

Summary of Docker build error
- Failing command/step
- RUN bazel build //:server (Dockerfile line 42)
- Exact error messages and exit code
- Exit code: 1
- Auto-Configuration Error: Cannot find gcc or CC; either correct your path or set the CC environment variable
- ERROR: no such package '@@rules_cc++cc_configure_extension+local_config_cc//':
- /workspace/selenium/BUILD.bazel:92:12: //:server depends on @@rules_cc++cc_configure_extension+local_config_cc//:cc-compiler-k8 in repository @@rules_cc++cc_configure_extension+local_config_cc which failed to fetch. no such package '@@rules_cc++cc_configure_extension+local_config_cc//':
- Analysis of target '//:server' failed; build aborted
- Context about the failure
- The failure occurs in the final Bazel build step of the Dockerfile:
- Dockerfile:42
- [8/8] RUN bazel build //:server
- Bazel version reported: 9.0.1 (Starting local Bazel server (9.0.1); bazel 9.0.1)
- Base image: ubuntu:jammy-20260217 (FROM docker.io/library/ubuntu:jammy-20260217)
- Missing packages/files or environment issues mentioned
- Missing compiler: Cannot find gcc or CC; either correct your path or set the CC environment variable
- Bazel rule dependency fetch failure: could not fetch @@rules_cc++cc_configure_extension+local_config_cc //:cc-compiler-k8 (no such package in repository @@rules_cc++cc_configure_extension+local_config_cc)
- Version mismatch information
- Bazel version used: 9.0.1
- Base image tag: ubuntu:jammy-20260217
- No explicit version mismatch is shown beyond the reported missing toolchain (gcc/CC) and the failed CC/configure repo fetch.# Base image with stable Debian/Ubuntu userland

Concerns: The Bazel wrapper is installed as /usr/local/bin/bazel but the downloaded file is bazelisk-linux-amd64; this will work if the binary is executable, but naming could be confusing and may affect scripts expecting bazelisk., No HEALTHCHECK defined in the Dockerfile; container health is not self-validated at runtime. Smoke [PASS]: java -version Smoke [PASS]: node -v Smoke [PASS]: test -x /usr/local/bin/bazel && echo bazel-wrapper-present || echo bazel-wrapper-missing
