The Daytona project handles configurations for projects through various options, including Dev Container, Docker, Kubernetes, and more. This section will cover the possible configuration options, provide examples for each option, and quote the source of information to build confidence.
Dev Container
Daytona supports Dev Container configurations, which allow developers to define a consistent and reproducible development environment. Dev Containers are built using Dockerfiles and are integrated with Visual Studio Code for a seamless development experience.
Here’s an example of a devcontainer.json configuration:
{
"name": "Go",
"image": "golang:1.17",
"extensions": [
"golang.go",
"editorconfig.editorconfig"
],
"customizations": {
"vscode": {
"settings": {
"go.gopath": "/workspace"
}
}
}
}

Docker
Daytona also supports Docker configuration, allowing developers to create Dockerfiles for building and running their applications.
Here’s an example of a Dockerfile:
FROM golang:1.17
WORKDIR /app
COPY go.mod ./
COPY go.sum ./
RUN go mod download
COPY *.go ./
RUN go build -o main .
CMD ["./main"]

Kubernetes
Daytona supports Kubernetes configuration through Kubernetes manifests (YAML or JSON files) and Helm charts.
Here’s an example of a Kubernetes deployment manifest:
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-app
spec:
replicas: 3
selector:
matchLabels:
app: my-app
template:
metadata:
labels:
app: my-app
spec:
containers:
- name: my-app
image: my-app:1.0.0
ports:
- containerPort: 8080

Customization
Daytona allows for customization through various configuration options. For example, developers can customize the Go build output directory by setting the GOOUT environment variable.
export GOOUT=/path/to/output/directory
Source: Go build documentation
Daytona also supports customizing the CNI (Container Network Interface) configuration for Kubernetes clusters.
Here’s an example of a CNI configuration:
{
"cniVersion": "0.3.1",
"name": "my-cni",
"plugins": [
{
"type": "portmap",
"capabilities": {
"portMappings": true
}
}
]
}

In addition, Daytona supports customizing the Open Policy Agent (OPA) configuration for policy-based control.
Here’s an example of an OPA configuration:
services:
authz:
path: /path/to/authz
policy: |
package authz
allow { input.user == "alice" }
Source: OPA configuration documentation
Dev Container and Other Formats
Daytona supports Dev Container configurations, which are built using Dockerfiles and integrated with Visual Studio Code. However, Daytona also supports other configuration formats, such as Kubernetes manifests, Helm charts, and Docker Compose files.
Here’s an example of a Docker Compose file:
version: "3.9"
services:
my-app:
image: my-app:1.0.0
ports:
- "8080:8080"
Source: Docker Compose documentation
Conclusion
Daytona supports various configuration options, including Dev Container, Docker, and Kubernetes. These configuration options allow developers to define consistent and reproducible development environments, build and run applications, and customize their development experience. By using these configuration options, developers can improve their productivity and deliver high-quality software.
