# Devfile components
<a name="devenvironment-devfile-components"></a>

Currently, CodeCatalyst only supports `container` components in your devfile. For more information, see [Adding components](https://devfile.io/docs/2.0.0/adding-components) in the Devfile.io documentation.

The following example shows you how to add a startup command to your container in your devfile.

```
components:
  - name: test
    container:
      image: public.ecr.aws/amazonlinux/amazonlinux:2
      command: ['sleep', 'infinity']
```

**Note**  
When the container has short lived entry command, you must include `command: ['sleep', 'infinity']` to keep the container running.

CodeCatalyst also supports the following properties in your container component: `args`, `env`, `mountSources`, and `volumeMounts`.
