More yc commands

  • Create registry and configure Docker
    yc container registry create --name <name> && yc container registry configure-docker

    Create CR and wire docker creds helper; modern: uses yc as a credential helper, no docker login

  • Push image to Container Registry
    docker tag <name>:<id> cr.yandex/$(yc container registry get --name <name> --format json | jq -r .id)/<name>:<id> && docker push cr.yandex/$(yc container registry get --name <name> --format json | jq -r .id)/<name>:<id>

    Tag with resolved registry id then push; avoids hardcoding the cr.yandex/<reg-id>

  • List registry images by repository
    yc container repository list --format json | jq -r '.[].name' | while read r; do yc container image list --repository-name "$r" --format json | jq -r '.[] | "\(.name):\(.tags[]? // "<none>")"'; done

    Enumerate every tag across all repos; useful before a registry GC sweep

  • Deploy serverless container revision
    yc serverless container create --name <name>; yc serverless container revision deploy --container-name <name> --image cr.yandex/<id>/<name>:<id> --cores 1 --memory 512M --service-account-id <id> --concurrency 4

    Roll out a new revision from a CR image; note: concurrency caps in-flight requests per instance

  • Read logs from a logging group since 1h
    yc logging read --group-name <name> --since 1h --levels ERROR,WARN --format json | jq -r '.[] | "\(.timestamp) \(.level) \(.message)"'

    Tail YC Cloud Logging filtered to ERROR/WARN; modern: --since accepts 1h/30m relative windows
