 Binary Data

binary data

In YAML, binary data is used to store: 👉 Non-text data (images, files, certificates, keys, etc.). Since YAML is text-based, binary data is encoded using: 👉 Base64 encoding

Binary data can be represented in YAML using Base64 encoding. This allows you to include binary data, such as images or files, within a YAML document.

converted → Base64 → stored as text

Srtucture:

file_content: !!binary |

SGVsbG8gRGV2T3Bz

file_data: !!binary |

R0lGODlhAQABAIAAAAUEBAgKACwAAAAAAAAQABAAACAkQBADs=

What happens internally:

Original data → Hello DevOps

Encoded → SGVsbG8gRGV2T3Bz

YAML stores → text safely

eg

certificate: !!binary |

apiVersion: v1

kind: Secret

data:

username: YWRtaW4=

password: cGFzc3dvcmQ=

to Decode Base64

Base64 → Decoded data

# echo "password" | base64

# cGFzc3dvcmQ=

# echo cGFzc3dvcmQ= | base64 --decode

# password

# echo cGFzc3dvcmQ= | base64 -d

# password

YAML decodes the Base64 encoded data back to its original form when it is read or processed.
