When using docker_clone_volume.sh, I found that when copying a volume with influxdb data, the clones image was bigger than the original. cause: alpine base image contains a cp version (busybox) which does _not_ preserve hardlinks, even with the -a option. This is fixed by using an ubuntu base image instead of alpine. downside: ubuntu image is larger than alpine. Source volume: influxdb_data 380.2 MB Before: influxdb_data.bak 443.5 MB After: influxdb_data.ubuntu.bak 380.2 MB |

docker-convenience-scripts
This repository will contain different convenience scripts for docker I have gathered over time.
docker_clone_volume.sh
The purpose for this script is that I can easily create a clone of an existing docker data with a new name. This will allow me to create a duplicate of an existing data volume I use in the production environment of my blog for example and take that duplicate to my development version to ensure I have the latest production data also at development.
You can find more details in my blog post Cloning Docker Data Volumes
docker_get_data_volume_info.sh
The purpose for this script is that I can easily get a list of details for all data volumes that are currently present. The information that is provided to the user as output is per data volume the current size of the data volume and a list of stopped or running containers that have a link to this data volume, including the image corresponding to the container. The script allows me to easily see if there are some data volumes on my disk that are taking up a lot of space and are not needed anymore.
