resolveContainerSecurityContext previously force-overwrote an override's Capabilities/Privileged with the base defaults unconditionally, so an operator setting AGENT_SECURITY_CONTEXT with capabilities.drop: ["ALL"] to satisfy OpenShift/PodSecurity restricted would still get the base's default SYS_PTRACE capability added back, causing admission to keep rejecting the pod. Found via Task 6's live restricted-admission e2e run. Now the override's own Capabilities/Privileged win when specified; base values are used only as a fallback when the override leaves them unset.
Reduce cyclomatic complexity in resolveContainerSecurityContext and several test functions by extracting shared assertion/lookup helpers; replace unbounded 'true' string literals with pkgconfig.BoolTrue (goconst); use the Go 1.26 new(x) value form instead of ptr.To for literal values (modernize); annotate the two operator-controlled variable-argument exec/file calls with justified #nosec comments, matching existing repo convention; wrap a >120-char line. task cli:lint:ci (CI's diff-scoped golangci-lint gate) now reports 0 issues for this branch.
Both file-path failure branches only wrapped the inline-YAML parse error, silently discarding the actual filesystem error (e.g. a typo'd AGENT_SECURITY_CONTEXT file path). Now wraps both, matching getPodTemplate's existing dual-wrap pattern it mirrors. Found during final whole-branch review of the SDD ledger's deferred Task 2 minor finding.
…r SecurityContext mergeContainer only copied a template-supplied container's whole SecurityContext when dst.SecurityContext was nil. Since Task 3's securityContextOptions.resolve() now always returns a non-nil SecurityContext (in every mode: default, STRICT_SECURITY, and AGENT_SECURITY_CONTEXT), that gate could never fire, so a POD_MANIFEST_TEMPLATE named-container securityContext override silently stopped taking effect in any mode -- contradicting the plan's own stated precedence and the driver.mdx docs this branch added, which tell OpenShift users to use exactly that override path. Found during an independent final-review pass (dispatched once AWS SSO recovered) that specifically caught what my own self-review of Task 6 missed. Replace the whole-struct swap with a field-level merge (mergeSecurityContext): every field the template sets wins, regardless of what STRICT_SECURITY/AGENT_SECURITY_CONTEXT resolved. Zero-change guarantee for the no-template case is unaffected (early return when the pod has no existing same-name container).
Scoped re-review of the template-precedence fix flagged two non-blocking coverage gaps: the init-container path only inherited correctness from mergeContainer/mergeSecurityContext by code-sharing inference, and default mode (neither STRICT_SECURITY nor AGENT_SECURITY_CONTEXT set) had no direct getContainers test proving POD_MANIFEST_TEMPLATE wins there too. Add one test for each.
mergeSecurityContext's flat 12-branch if-chain was suppressed with //nolint:cyclop instead of actually addressed. Replace it with a generic overrideIfSet[T] helper applied once per field: the loop body is now 12 straight-line calls to a 2-branch generic function instead of one 12-branch function, so the real complexity drops below the threshold with no suppression and no behavior change. task cli:lint:ci: 0 issues, no nolint directives in this package.

changed the title
getContainers took 9 positional params (pod, imageName, entrypoint,
args, envVars, volumeMounts, resources, security,
daemonConfigSecretName), well over revive's argument-limit (max 4).
This escaped the diff-scoped cli:lint:ci gate (a --new-from-patch
line-alignment quirk on the unchanged 'func getContainers(' text)
but is flagged by plain golangci-lint run ./..., matching the
project's actual lint config.
Bundle everything but pod into a devsyContainerInputs struct,
matching the existing podSpecInputs pattern already used in this
file for assemblePodSpec. Update the one production call site and
all 7 test call sites; extract testImageName/testEntrypoint consts
in run_test.go to fix a goconst finding the refactor introduced.
Confirmed via golangci-lint run ./pkg/driver/kubernetes/...: the
argument-limit finding on getContainers is gone; the only remaining
issues are pre-existing ones in files this branch never touches.
…e2e test CI's up-provider-kubernetes-restricted-scc job hung indefinitely in ContainerCreating: this repo's pinned kind node image predates the fix for kubernetes-sigs/kind#4178, where hostUsers: false makes every pod loop-fail sandbox creation via kind's mount-product-files.sh OCI hook (fixed in kind PR #4179, which lives in kind's node-image build -- bumping the repo-wide pinned node image is out of scope and risky for every other kind-based e2e job). Kubernetes Pod Security Admission "restricted" -- what this test actually exercises -- does not check hostUsers at all; it's an OpenShift-SCC-only concern already covered by 4 unit tests (TestFinalizePodSpecSetsHostUsersFalseWhenStrict and friends). Override hostUsers to true via POD_MANIFEST_TEMPLATE, which finalizePodSpec already respects, sidestepping the kind bug without weakening what this e2e test uniquely proves: real PSA-restricted admission plus a functional non-root workspace. Verified locally against a fresh kind cluster: the pod now leaves ContainerCreating in ~15s (previously hung for the full 3-minute SpecTimeout).
…gacy inject CI's restricted-scc e2e job hit a real (not sandbox-specific) failure after the hostUsers fix: the pod now admits and runs, but agent delivery over the exec stream stalled after a successful WebSocket protocol upgrade (repeated 'Websocket Ping failed'/i/o timeout for ~90s), then fell straight through to legacy inject, which then needs sudo the non-root container doesn't have. client-go's FallbackExecutor (pkg/driver/kubernetes/client.go) only falls back from WebSocket to SPDY on upgrade failure, never on a mid-stream stall in an already-upgraded connection -- so a single transient network hiccup between the client and the cluster's API server, which self-heals on retry, was treated as fatal. The same exec/delivery code path is shared by the already-passing root-container up-provider-kubernetes test, and AGENT_SECURITY_CONTEXT/STRICT_SECURITY only ever touch RunAsUser/RunAsGroup/RunAsNonRoot/hostUsers -- nothing in that path plausibly explains a TCP-level stall, so this is a pre-existing delivery-robustness gap that benefits every Kubernetes user, not an OpenShift-specific fix. Add one bounded retry around the native delivery attempt before falling back, and give the restricted-scc test enough SpecTimeout budget (3m -> 5m) to accommodate a retried stall without cutting the legacy-inject path off mid-flight.
…edesign retryNativeDelivery blindly retried the whole exec-stream attempt twice with no error classification and no per-attempt deadline: a genuinely broken transport paid the full ~90s OS-level TCP timeout cost twice before falling back, and a permanent failure (e.g. no curl in the image) would have been retried identically for no benefit. Root cause: streaming the multi-hundred-MB agent binary over exec-stdin is itself the fragile part of KubernetesDelivery -- reproduced locally against a real kind cluster (standalone Client.Exec calls with the same 170MB payload succeeded in ~500ms every time; the same code invoked from inside devsy's own subprocess architecture stalled every time). Legacy inject already trusts an established alternative for this (pkg/inject/inject.sh's download_binary): have the container fetch its own binary via curl/wget instead of receiving its bytes from the host. KubernetesDelivery.DeliverPostStart now: - Prefers an in-container download (a short, no-stdin exec call -- proven reliable in every local repro) over exec-stdin streaming. - Classifies exec-stream failures: only a transient failure (i/o timeout, broken pipe, connection reset, or our own attempt deadline firing) is retried; a permanent one (real exit code, missing shell) fails immediately instead of paying the same cost twice. - Bounds each exec-stream attempt to a real deadline (30s) instead of the OS's ~90s TCP timeout, making the classified retry cheap enough to be worth doing at all. Also fixes a latent bug found during investigation: Client.Exec's ctx-cancellation path discarded the real error and returned nil on cancellation, which would have silently reported a deliberately aborted (e.g. deadline-exceeded) attempt as a successful delivery -- load-bearing for the new attempt deadline to be trustworthy. Verified against a real kind cluster reproducing the exact CI failure: total delivery time before falling back to legacy inject dropped from an unbounded multi-minute hang to a bounded, predictable ~3m24s, with every tier now failing fast and for a classified reason instead of being masked by blind retry.
The injected devsy/devsy-init containers hardcode
/usr/local/bin/devsy as the agent install path, which requires root
to write. On OpenShift's restricted SCC (or any non-root
AGENT_SECURITY_CONTEXT/STRICT_SECURITY configuration), the container
runs as an assigned non-root UID and can't write there, so agent
delivery and the su-based SSH/tunnel command construction both fail
silently or crash-loop.
Add AGENT_INSTALL_PATH to let operators point the install path at a
writable mount (e.g. under WORKSPACE_VOLUME_MOUNT). Thread it through:
- ProviderAgentConfig.ContainerInstallPath()/RunsFixedNonRootUser(),
shared by the ssh/tunnel command builder and the kubernetes driver
so su-wrapping is skipped when the container is already fixed
non-root.
- KubernetesDelivery.InstallPath, so postStart delivery installs to
the same path the container expects.
- resolveAgentKubernetesConfig, so the option flows from
provider.yaml through to ProviderKubernetesDriverConfig.
Non-root containers (e.g. an OpenShift restricted-SCC pod) can't
write /etc/gitconfig, /var/run/devsy/result.json, or /var/devsy:
- configureSystemGitCredentials required the system git config
scope; fall back to the process user's global config when the
system file isn't writable ("add git config: permission
denied").
- writeResultFile hardcoded DevContainerResultPath under
/var/run/devsy; fall back to DevContainerResultFallbackPath
under the OS temp dir, and read it back via
ReadDevContainerResultCommand() so both host and container agree
on which path holds the result.
- containerDataDir() (setupKubeConfig/marker files) falls back to
an OS-temp-backed directory when /var/devsy can't be created,
cached for the process lifetime since MkdirAll is probed on
every marker check.
KubernetesDelivery.DeliverPostStart unconditionally preferred having the pod download its own binary, even when the caller's BinarySource resolves from a local dev build or an explicit path override. That meant a locally-built agent binary (e.g. this repo's own build, or DEVSY_AGENT_BINARY) was never actually exercised in the pod: the container downloaded the published release instead. Add BinaryManager.HasLocalOverride(arch) to report when the host can supply the bytes directly -- an env override, or the process's own executable when its OS/arch matches the container's -- and wire PostStartOptions.PreferInContainerDownload from !mgr.HasLocalOverride(arch) so postStart delivery only takes the download shortcut when it would resolve to a network download anyway. Add AGENT_INSTALL_PATH to the restricted-scc e2e test so the in-cluster verification exercises a real non-root writable path.

Inline comments:
In `@cmd/internal/agentcontainer/setup.go`:
- Line 904: Update the cleanup around gitConfig.Unset for credential.helper so
it removes only the gitCredentials entry installed by setup, rather than
unsetting the entire key. Use value-specific Git configuration cleanup or
restore the helper values captured before gitConfig.Add, preserving any
pre-existing helpers and ensuring cleanup succeeds with multiple values.
In `@cmd/workspace/ssh.go`:
- Around line 474-476: Update the startTunnel flow used by startProxyTunnel so
it preserves and passes the resolved agent configuration even when the client is
a ProxyClient that does not implement WorkspaceClient. Replace the zero-value
fallback around the WorkspaceClient assertion with the existing agent config, or
expose that config through the proxy-client contract, so buildSSHServerCommand
uses the configured AGENT_INSTALL_PATH.
- Line 599: Update the su decision in the SSH command flow to use the effective
run-as user/group fields rather than RunsFixedNonRootUser(), ensuring
capability-only AGENT_SECURITY_CONTEXT with a root container default still
switches to cmd.User. Add a regression test covering this configuration with a
non-root SSH user and verify the SSH server does not run as root.
In `@pkg/agent/delivery/kubernetes.go`:
- Around line 209-212: Quote destPath with shellescape.Quote before constructing
the exec-stream fallback script, and use the quoted value for every destPath
interpolation in the dirname, mktemp, and mv commands while preserving the
existing cleanup and failure behavior.
In `@pkg/devcontainer/setup/setup.go`:
- Line 632: Update the ContainerDataDir selection logic around os.MkdirAll to
probe actual write access after ensuring the directory exists, such as by
creating and cleaning up a temporary file or directory within it. If the probe
fails, select /tmp/devsy-data before containerDataDir caches the path,
preserving the existing marker-write behavior.
In `@pkg/driver/kubernetes/client.go`:
- Line 160: Update waitForStream’s errChan handling so that when the received
err is nil, it checks whether the context was canceled and returns ctx.Err() if
so; otherwise preserve the successful nil return and existing non-nil error
behavior.
In `@pkg/driver/kubernetes/helper.go`:
- Around line 165-172: Update the security-context YAML parsing flow so the file
unmarshal result is assigned to the existing outer err variable before checking
success. Ensure the final error in the helper wraps the actual file YAML parse
error rather than a shadowed nil read error, while preserving the successful
return path.
In `@pkg/provider/provider.go`:
- Line 175: Update the security decision in RunsFixedNonRootUser so
configuration presence alone does not mark execution as non-root; require an
effective non-root user and runAsNonRoot configuration that guarantees it.
Preserve the fallback to su in buildSSHServerCommand whenever effective non-root
execution is not established, including partial contexts and strict mode before
cluster assignment.
In `@sites/docs-devsy-sh/content/docs/developing-providers/driver.mdx`:
- Line 78: Update the strictSecurity documentation to describe its actual
behavior: clear only the run-as fields, retain capabilities and Privileged, and
set hostUsers to false; remove the inaccurate claim that it removes the entire
default security context and merges the podManifestTemplate context.

- Line 121: Update FactoryOptions and the factory construction flow to carry the
resolved workspace download URL into LegacyShellDelivery instead of assigning an

resolution used by RunsFixedNonRootUser() to retain pod-level runAsUser and
runAsNonRoot from spec.securityContext. Apply precedence in this order:
container-level values, then AGENT_SECURITY_CONTEXT values, then pod-level
values, preserving existing behavior when higher-priority fields are set.

In `@e2e/README.md`:
- Line 20: Update the Kind cluster setup documentation next to the direct kind
create cluster command to state that Kind v0.33.0 or newer is required for
Kubernetes v1.36.4, or direct users to task cli:test:e2e:kind:setup where the
prerequisite is enforced.
In `@pkg/config/paths_test.go`:
- Line 88: Update runResultCommandTest to check exec.LookPath("sh") before
invoking the shell command, and skip the test when the executable is
unavailable; preserve the existing command assertions on platforms where sh
exists.
In `@pkg/devcontainer/setup/container_data_dir_test.go`:
- Line 28: Update the test setup around os.Mkdir before securedContainerDataDir
to call os.Chmod(dir, 0o777), then stat and verify the directory has mode 0o777
before testing normalization. Fail the test if chmod or mode verification fails,
ensuring the permission-narrowing path is exercised despite the process umask.
In `@sites/docs-devsy-sh/content/docs/developing-providers/driver.mdx`:
- Line 81: Update the kubernetesUserNamespaces documentation to state that
UserNamespacesSupport is disabled by default in Kubernetes 1.30–1.32, enabled by
default in 1.33–1.35, and becomes GA with the gate locked on in 1.36; preserve
the surrounding user-namespace and node-support guidance.

Issue request #2 ("disable agent container injection entirely") is not implemented. The injected container's
Command/Argsare the workspace process (credential sync, inactivity timeout, exec/attach session multiplexing all run as its PID 1) — there's no separate sidecar to toggle off without redesigning the driver's execution model.

Live-tested against a real

Note Kubernetes PSArestrictedisn't identical to OpenShift's SCC (it doesn't enforce SCC's allocated UID range), so this is strong evidence, not a substitute for validation on a real OpenShift cluster.Summary by CodeRabbit
