For some Docker operations we need to know the ID of a particular container. We can find this out if we know the name of the container by using a few tricks.
Here's what I've written (so far):
Baeldung on Java
- Docker (2)
Learn how to list Docker volumes and get detailed information about them.
Baeldung on Linux
- Scripting (9)
- Files (4)
- Filesystems (2)
- Administration (2)
- File Viewing (1)
- File Searching (1)
We look at ways to clean up unused resources and move Docker storage in order to avoid storage capacity errors.
Linux supports multiple file systems. We look at how to find out which file system is in use by a given device. We also explore loop devices, which can be used to try out different types of file system.
A Docker container mixes file system elements from images, volumes and its own read-write layers. We look at a few commands to help understand which space is taken by our Docker containers, and where it comes from.
vim can be a useful tool for reviewing the differences between files in Linux. We look at how to use it, how it compares with diff, and how to integrate it with git.
We can convert files between different delimited formats using tools readily available in our Linux distros. We look at how to convert to CSV format using tr, awk, and sed.
