Thank you for your answer.
This is a great idea.
Unfortunately, our exploitation zone and current architecture does not
allow this.
The whole disk where is stored catalogs and TDS conf files is read-only
(for containers).
This is why I wanted to split the content folder, catalogs on one side
and cache/logs on another.
I already configured the log path in the *log4j* conf file.
About the cache, for the moment I defined the *<dir>* attribute in
*threddsConfig.xml* for each cache.
Kind regards,
Enzo

Good morning,
A possibility would also be to mount the configuration directory as a
read-only volume, and mount a second directory as writable in the
subdirectory named cache.
/ read-only container rootfs
/home/tomcat/content/thredds read-only
/home/tomcat/content/thredds/cache writable
Consider the following as pseudo code to illustrate one way to
accomplish this when starting a container instance with the docker
command line:
docker run --read-only -v
/host/tds-config:/home/tomcat/content/thredds:ro -v
/host/tds-cache:/home/tomcat/content/thredds/cache:rw container-image
Notice that there also are other directories beneath the configuration
directory that TDS expects to be writable, e.g. logs etc. TDSv5 also
populates the content directory with example files that it cannot find
during startup. You need to put your own files there in advance or
just use "touch" to create empty files for the paths of the example
files before starting TDS to avoid TDSv5 to crash on startup.

Dear all,
On Thredds 4.6, is there any way to change the cache directory,
other than defining a symlink?
I would like a read-only folder for my content directory, mounted
as a volume for my dockered Thredds.
According to TDS Configuration file
<https://docs.unidata.ucar.edu/tds/4.6/adminguide/reference/ThreddsConfigXMLFile.html>,
I can define a directory for each cache.
But it would be easier to redefine a single path, right?
Kind regards,
Enzo
