As the question title specifies , i have to replace a block to text in a file with a new block of text

For a task like this, you could just use existing commands rather than reinventing the wheel:

Different results with docker run and docker-compose?

Asked 2020-Aug-18 at 09:29

I'm using this image to mount an unionfs filesystem. When I run the container with docker run, it works perfectly, but when I put the same conditions into docker-compose, it doesn't work. It seem to be an issue with the environmental variable (I suspect).

docker-compose config:

The problem here are the quotes, which are treated differently, as you specify the variables in a yaml-file.

You need to write it like this:

Both path_fr and path_to contain quoted strings. Thus path_fr is NOT a part of path.

QUESTION

How file lookup work in Docker container

Asked 2017-Sep-14 at 18:12

According to Docker docs, every Dockerfile instruction create a layer, and all the layers are kept when you create new image based on an old one. Then when I create my own image, I might have hundreds of layers involved because of the recursive inherit of layers of base image.

In my understand, file lookup in container work this way:

process want to access file a, lookup starts from the container layer(thin w/r layer) .
UnionFS check whether this layer have a record for it (have it or marked as deleted). If yes, return it or say not found respectively, ending the lookup. If no, pass the task to the layer below.
the lookup end at the bottom layer.

If that is the way, consider a file that resides in the bottom layer and unchanged by other layers, /bin/sh maybe, would need going through all the layers to the bottom. Though the layers might be very light-weight, a lookup still need 100x time than a regular one, noticeable. But from my experience, Docker is pretty fast, almost same as a native OS. Where am I wrong?

This is all thanks to UnionFS and Union mounts!

Straight from wikipedia:

It allows files and directories of separate file systems, known as branches, to be transparently overlaid, forming a single coherent file system.

And from an interesting article:

In the kernel, the filesystems are stacked in order of their mount sequence, the first mounted filesystem is at the bottom of the mount stack, and the latest mount is at the top of the stack. Only the files and directories of the top of the mount stack are visible. With union mounts, directory entries from the lower filesystems are merged with the directory entries of upper filesystem, thus making a logical combination of all mounted filesystems. Files with the same name in a lower filesystem are masked, as the upper one takes precedence.

So it doesn't "go through layers" in the conventional sense (e.g one at a time) but rather it knows (at any given time) which file resides on which disk.

Doing this in the filesystem layer also means none of the software has to worry about where the file resides, it knows to ask for /bin/sh and the filesystem knows where to get it.

More info can be found in this webinar.

So to answer your question:

Where am I wrong?

You are thinking that it has to look through the layers one at a time while it doesn't have to do that. (UnionFS is awesome!)
