# Get Setting (Deprecated)

:::warning Deprecated
`cloudposse/github-action-atmos-get-setting` is deprecated. Use [`atmos list settings --query`](/cli/commands/list/settings) to extract a setting across stacks, or [`atmos describe component --query`](/cli/commands/describe/component) to read a single setting from one component/stack, directly in your workflow — no wrapper action needed.
:::

The [Atmos Get Setting GitHub Action](https://github.com/cloudposse/github-action-atmos-get-setting) retrieved a single setting, or a group of settings, from Atmos configuration and exposed them as GitHub Action outputs.

## Native CI Equivalent

```yaml
- name: Read a setting
  run: |
    {
      delimiter="$(dd if=/dev/urandom bs=15 count=1 status=none | base64)"
      echo "value<<$delimiter"
      atmos describe component vpc -s plat-ue2-prod --query .settings.some_key
      echo "$delimiter"
    } >> "$GITHUB_OUTPUT"
```

The multiline delimiter form handles any setting value safely, including ones with embedded newlines — a plain `value=$(...)` assignment can silently split into multiple `$GITHUB_OUTPUT` records if the query result isn't a single-line scalar. Generate the delimiter per-write from random bytes (rather than a fixed string like `EOF`) so a setting value that happens to contain a line matching the delimiter can't prematurely close it. `dd`/`base64` are available in the Atmos container's `debian:trixie-slim` base without installing anything extra — `uuidgen` would require the `uuid-runtime` package, which isn't installed there.

Use [`--query`](/cli/commands/describe/component) to pull a single value out of a component/stack, or [`atmos list settings --query`](/cli/commands/list/settings) to compare the same setting across every stack in a table.
