**ID:** `docker-best-practices/multiple-healthcheck`

**Language:** Docker

**Severity:** Notice

**Category:** Best Practices

## Description{% #description %}

A Dockerfile with multiple `HEALTHCHECK` instructions is confusing. A container should only have one `HEALTHCHECK` instruction.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```docker
HEALTHCHECK CMD foo
HEALTHCHECK CMD bar
```

## Compliant Code Examples{% #compliant-code-examples %}

```docker
HEALTHCHECK CMD foo
```
