TL;DR

Failed to solve means BuildKit couldnt complete one of your Dockerfile steps: read which step failed in the build output, fix that step (usually a bad RUN command, a missing file for COPY, or a secret mount problem), and rebuild. The error names the failing step if you look past the summary line.

The error

ERROR: failed to solve: process "/bin/sh -c npm ci" did not complete successfully: exit code: 1

Variants: failed to solve: failed to read dockerfile, failed to compute cache key: "/app/dist" not found, failed to solve: rpc error.

Use this when

• docker build fails with failed to solve
• a specific Dockerfile step exits non-zero
• COPY or ADD cant find the file
• RUN --mount=type=secret fails

Not for

• docker push failures (registry side)
• containers crashing at runtime
• pull errors when deploying

Steps

1. Find the failing step. Rebuild with plain progress to see it clearly:

docker build --progress=plain -t myapp:test . 2>&1 | grep -B 5 "ERROR"

Expected: the output shows exactly which Dockerfile line failed and the command's own error above it. The command's error is the real error; failed to solve is just the wrapper.

2. If a RUN step failed, reproduce it interactively:

docker build --target [earlier-stage] -t debug-stage .
docker run --rm -it debug-stage sh

Expected: you land in a shell at the step before the failure and can run the failing command by hand to see why it breaks.

3. Fix the common causes:

• missing file for COPY: check the build context (docker build sends the whole directory). Add a .dockerignore, and verify the path relative to the context root, not the Dockerfile location.
• apt/apk/yum failing: the base image moved or the package index is stale. Pin versions and run the update and install in one RUN layer.
• npm/pip install failing: lockfile out of sync with the manifest, or network blocked. Copy lockfiles first and install before copying source.
• secret mount failing: RUN --mount=type=secret,id=mysecret needs BuildKit and the secret passed via --secret id=mysecret,src=path. The src file must exist on the host.

4. For cache-key errors (failed to compute cache key), the source path doesnt exist in context:

ls -la [the-path-from-the-error]

Expected: the path is missing or misspelled. Fix the Dockerfile path or the .dockerignore that excluded it.

5. If the Dockerfile itself wont parse, validate the syntax:

docker build --check -t myapp:test .

Expected: reports the parse problem with a line number. Common: bad JSON array syntax in CMD/ENTRYPOINT, or a heredoc gone wrong.

6. Rebuild clean to confirm:

docker build --no-cache -t myapp:test .

Expected: build completes, image tagged. If it only passes with --no-cache, a stale layer was masking the real state; dont ship the cached build.

Variant: failed to solve only in CI, works locally

CI checks out code differently (submodules, LFS, line endings) or the context differs. Print ls of the context in CI and diff against local.

Variant: rpc error / connection reset during build

BuildKit daemon hiccup, not your Dockerfile. Restart the builder (docker buildx rm / recreate) and retry.

Variant: multi-platform build fails on one arch

The failing step assumes the host arch (downloads an x86 binary on arm64). Gate arch-specific steps with TARGETARCH or use multi-arch base images.

Why it happens

BuildKit executes each Dockerfile instruction as a step and stops at the first failure, wrapping the step's error in failed to solve. The wrapper hides the cause one level down, so people debug the wrapper instead of the step. Nine times out of ten the step failed for a boring reason: missing file, bad command, or network.

Edge cases

• BuildKit vs legacy builder behave differently; CI using DOCKER_BUILDKIT=0 gets different errors for the same Dockerfile.
• Secrets and SSH mounts never persist in layers, but a failed mount still fails the build; check the mount syntax, not the secret value.
• Very large contexts slow every build and cause cache-key weirdness; .dockerignore is not optional.
• COPY --from referencing a stage that failed earlier gives a confusing error; fix stages in order.

Thread query: "docker build" fails with "failed to solve" error

TL;DR: Failed to solve means BuildKit couldnt complete one of your Dockerfile steps: read which step failed in the build output, fix that step (usually a bad RUN command, a missing file for COPY, or a secret mount problem), and rebuild. The error names the failing step if you look past the summary line.

TL;DR

A failing RUN line means the command exited nonzero inside the build container, and buildx hides the real error a few lines above the failure marker. Rerun the build with plain progress output to see the failing command's own stderr, then reproduce the exact command outside the build.

process '/bin/sh -c ...' did not complete successfully: exit code: [N]

Steps

1. Rerun the build with plain progress so the failing command's output is visible:

docker buildx build --progress=plain --no-cache -t [IMAGE]:[TAG] -f [DOCKERFILE] [CONTEXT] | tee [LOGFILE]

Expected: the log shows the exact RUN line plus the command's own error output just above the failure marker. Read upward, not at the marker itself.

2. Identify the failing stage and line from the log:

grep -n "did not complete successfully" [LOGFILE]

Expected: the step number and the /bin/sh -c invocation that failed.

3. Reproduce the failing command in a matching base image to iterate fast:

docker run --rm -it [BASE_IMAGE]:[TAG] sh

Expected: an interactive shell in the same base image, where you can paste the failing RUN body line by line and see which part exits nonzero.

4. Once the culprit is found, harden the RUN line so the failure is loud and located:

RUN set -eux; \
    [COMMAND_ONE]; \
    [COMMAND_TWO]

Expected: the build log now prints each command before running it (-x) and stops at the first failure (-e), instead of one opaque line.

5. Rebuild and confirm the step passes:

docker buildx build --progress=plain -t [IMAGE]:[TAG] -f [DOCKERFILE] [CONTEXT]

Expected: the previously failing step completes and the build proceeds to the next stage.

When to use

• docker buildx build fails with a /bin/sh -c nonzero exit on a RUN line
• A Dockerfile that builds locally fails in CI on the same step
• Multi-stage builds fail in a later stage with package or compile errors

When not to use

• The failure is COPY failed: no such file or a missing build arg, which is a context problem, not a command failure
• Buildx fails with daemon or builder errors before any step runs
• The failure is a flaky network fetch inside the step; see the step about retrying before rewriting the command

Why it happens

Each RUN line executes as a single /bin/sh -c string, so the first failing subcommand aborts the rest and buildx reports only the wrapper's exit code. In CI the default progress output also collapses step logs, hiding the command's own stderr. Locally cached layers can additionally mask the failure because the bad step never reruns.

Edge cases

• set -e does not catch failures inside pipes unless pipefail is set; add set -o pipefail when the line pipes output
• APT or APK transient network errors fail the step with exit 100; retry the fetch with a retry flag or a small retry loop rather than restructuring the Dockerfile
• Commands that succeed with warnings locally can fail under set -e if they return nonzero on warnings; check the actual exit code before blaming the tool
• BuildKit cache mounts can persist a corrupted state between builds; --no-cache is the honest rerun when debugging
