Sonatype Nexus Docker Registry - Disc Consumption

Sonatype Nexus Repository

I recently switched to using the Sonatype Nexus Repository for hosting my Docker images. Previously, I used the Docker registry image to store my Docker images.

With approximately 30 Docker images, the Docker registry image consumed around 13GB of space. However, after switching to the Sonatype Nexus image, the storage usage has increased to about 22GB which is huge.

I’m unable to pinpoint the cause of this significant increase in storage consumption. Any assistance in identifying and resolving this issue would be greatly appreciated.

with this data, I am creating the repo…

'{
  "name": "'$docker_hosted_repository_name'",
  "online": true,
  "storage": {
    "blobStoreName": "default",
    "strictContentTypeValidation": true,
    "writePolicy": "allow"
  },
  "component": {
    "proprietaryComponents": true
  },
  "docker": {
    "v1Enabled": false,
    "forceBasicAuth": true,
    "httpPort": '$docker_port'
   }
}'

Thanks in advance.

Are you running the Compact Blobstore task? That will remove soft-deleted binaries permanently. Without that, they’ll accumulate.

I am not running tasks I am just creating and pushing my images…, I am guessing, the images are not storing by sharing common layers of docker images, is there any way that I can configure to use the shared layers if yes?
