atmos vendor update
Check each Git-backed source in your vendor.yaml for a newer version — honoring any
per-source constraints — and update the version field in place, preserving comments,
anchors, and Go templates such as {{.Version}} in source URLs.
Usage
atmos vendor update [--check] [--pull] [--component <name>] [--tags <a,b>] [--outdated] [--component-manifests]
Sources whose version is templated ({{...}}) or whose source is not a Git repository
are skipped and reported. Updates are written to the file that declares each source,
including imported manifests — a component declared in vendor.yaml has its
spec.sources[].version updated, while a component resolved from a per-component
component.yaml has its spec.source.version updated instead.
If --component isn't declared in vendor.yaml — or no vendor.yaml exists — Atmos falls
back to the component's own component.yaml/component.yml manifest, matching
atmos vendor pull's existing precedence:
vendor.yaml wins whenever it declares the component. Without --component, a repo-wide
sweep of every component.yaml found under each component type's base path runs
automatically whenever no vendor.yaml exists — a repo that vendors exclusively via
component.yaml works with no extra flag. Add --component-manifests to also run that
sweep alongside an existing vendor.yaml (for repos that mix both manifest styles).
Examples
# Dry run: show what would be updated.
atmos vendor update --check
# Update all Git-backed sources.
atmos vendor update
# Update versions and then pull the new components.
atmos vendor update --pull
# Update a single component, or by tags.
atmos vendor update --component vpc
atmos vendor update --tags networking,aws
# Show only sources with an available update.
atmos vendor update --check --outdated
# Also sweep per-component component.yaml manifests alongside an existing vendor.yaml.
atmos vendor update --check --component-manifests
Version constraints
Per-source constraints control which upstream versions are eligible:
sources:
- component: "vpc"
source: "github.com/cloudposse/terraform-aws-components"
version: "1.323.0"
constraints:
version: "^1.0.0" # semver constraint (Masterminds/semver)
excluded_versions:
- "1.2.3" # a specific bad version
- "1.5.*" # an entire broken series
no_prereleases: true # skip alpha/beta/rc
Flags
--check- Dry run: show available updates without modifying any files.
--pull- After updating versions, run
atmos vendor pull. --component/-c(string)- Update only this component.
--tags(string)- Update only components carrying any of these comma-separated tags.
--outdated- Show only sources with an available update.
--type/-t(string, defaultterraform)- Component type (
terraform,helmfile, orpacker), used when falling back to a per-componentcomponent.yaml, or to restrict a--component-manifestssweep to one type. --component-manifests- Also check per-component
component.yamlmanifests when avendor.yamlis present (this sweep runs automatically when novendor.yamlexists). Only applies when--componentis not set. --file(string, default./vendor.yaml)- The vendor manifest to start from (imports are followed).
Version detection is supported for Git sources only (tags via git ls-remote), which
covers GitHub, GitLab, Bitbucket, and self-hosted Git. OCI, S3, GCS, and HTTP sources
are skipped. Private repositories are not yet supported.
