Eve Pipelines and Workflows

Use these patterns to automate build and deploy actions and invoke workflow jobs.

Pipelines (v2 steps)

• Define pipelines under pipelines in .eve/manifest.yaml.
• Steps can be action, script, or agent.
• Use depends_on to control ordering.
• Built-in actions include build, release, deploy, run, job, create-pr.
• Run manually:

- eve pipeline list - eve pipeline show <project> <name> - eve pipeline run <name> --ref <sha> --env <env> --repo-dir./my-app

• Trigger blocks exist in the manifest; GitHub and Slack webhooks can create pipeline runs.

Built-in Actions

build action

Build actions create BuildSpec and BuildRun records that are tracked and observable:

• Creates BuildSpec (defines what to build) and BuildRun (execution record) in the database
• Outputs include build_id and image_digests map (service name to SHA256 digest)
• These outputs automatically flow to dependent steps (release uses build_id)
• Inspect builds independently: eve build show, eve build diagnose, eve build runs, eve build logs

Agent steps

Use agent steps when a pipeline stage should run an AI agent job:

pipelines:
  remediation:
    steps:
      - name: analyze
        agent:
          prompt: "Analyze the failure and propose a fix"

Canonical pipeline flow

Every deploy pipeline should follow this pattern:

pipelines:
  deploy:
    steps:
      - name: build
        action:
          type: build
          # Creates BuildSpec + BuildRun, outputs build_id + image_digests
      - name: release
        depends_on: [build]
        action:
          type: release
          # References build_id, derives digests from BuildArtifacts
      - name: deploy
        depends_on: [release]
        action:
          type: deploy
          env_name: staging
          # Uses digest-based image refs for immutable deploys

Promotion workflow

Build once in test, then promote the same build artifacts to staging/production:

• The build step creates a BuildRun with artifacts (image digests)
• Releases carry the build_id forward, ensuring identical images across environments
• This pattern guarantees you deploy exactly what you tested

Track pipeline execution:

eve job list --phase active
eve job follow <job-id>
eve job result <job-id>

Pipeline Logs & Streaming

Monitor pipeline runs in real time:

# Snapshot logs for a run
eve pipeline logs <pipeline> <run-id>

# Real-time SSE streaming
eve pipeline logs <pipeline> <run-id> --follow

# Stream specific step
eve pipeline logs <pipeline> <run-id> --follow --step <name>

Failed steps include failure hints and link to build diagnostics when applicable.

Environment Deploy as Pipeline Alias

When an environment has a pipeline configured in the manifest, eve env deploy <env> --ref <sha> automatically triggers that pipeline instead of doing a direct deploy.

Basic usage

# Triggers the configured pipeline for test environment
eve env deploy test --ref 0123456789abcdef0123456789abcdef01234567

# Pass inputs to the pipeline
eve env deploy staging --ref 0123456789abcdef0123456789abcdef01234567 --inputs '{"release_id":"rel_xxx"}'

# Bypass pipeline and do direct deploy
eve env deploy staging --ref 0123456789abcdef0123456789abcdef01234567 --direct

Promotion flow example

# 1. Build and deploy to test environment
eve env deploy test --ref 0123456789abcdef0123456789abcdef01234567

# 2. Get release info from the test build
eve release resolve v1.2.3
# Output: rel_xxx

# 3. Promote to staging using the release_id
eve env deploy staging --ref 0123456789abcdef0123456789abcdef01234567 --inputs '{"release_id":"rel_xxx"}'

Key behaviors

• If environments.<env>.pipeline is set, eve env deploy <env> triggers that pipeline
• Use --direct flag to bypass the pipeline and perform a direct deploy
• Use --inputs '{"key":"value"}' to pass inputs to the pipeline run
• Default inputs can be configured via environments.<env>.pipeline_inputs in the manifest
• The --ref flag specifies which git SHA to deploy (40-character SHA or ref resolved via --repo-dir)
• Environment variables and secrets are interpolated as usual

This pattern enables promotion workflows where you build once in a lower environment and promote the same artifact through higher environments.

Workflows

• Define workflows under workflows in the manifest.
• db_access is honored when present (read_only, read_write).
• Invoke manually:

- eve workflow list - eve workflow show <project> <name> - eve workflow run <project> <name> --input '{"k":"v"}' (fire-and-forget) - eve workflow invoke <project> <name> --input '{"k":"v"}' (wait for result) - eve workflow logs <job-id>

• Invocation creates a job; track it with normal job commands.

Workflow Hints

Control gating, timeouts, and harness preferences via hints:

workflows:
  remediate:
    hints:
      gates: ["remediate:proj_abc123:staging"]
