Below is an error message when I try a create a blobstore for geowebcache. It would clearly seem that the problem is the directory is not writable. I have tried numerous things and am getting more confused. Setting the directory to 777, creating/adding groups/users to get the tomcat user access and altering tomcat9.service as follows..
/etc/systemd/system/multi-user.target.wants/tomcat9.service # Security User=tomcat Group=tomcat PrivateTmp=yes AmbientCapabilities=CAP_NET_BIND_SERVICE NoNewPrivileges=true CacheDirectory=tomcat9 CacheDirectoryMode=750 ProtectSystem=strict ReadWritePaths=/etc/tomcat9/Catalina/ ReadWritePaths=/var/lib/tomcat9/webapps/ ReadWritePaths=/var/log/tomcat9/ ReadWritePaths=/geoserver-blobstore This is confusing because of context...I fired up an Azure Ubuntu 20.04 VM and went through the Geoserver Instructions to install the nice and easy Jetty version: https://docs.geoserver.org/maintain/en/user/installation/linux.html All worked fine and I created layers and published data etc.. I could also add a blobstore at the /geoserver-blobstore location without any errors. This blobstore is a mounted managed Azure disk. Okay, so this was my test bed but I needed to make it more robust and secure so decided to start again on the same VM. I removed the GeoServer install. Installed Tomcat9, secured it with certbot certs, redirected 8080 to 8443 and have a DNS domain name pointing to it, which all worked fine. I dropped the geoserver.war file into the webapps folder, started Tomcat and geoserver is working under https at our domain name. Except for this error message when trying to configure the blobstore... Only obvious difference is the Tomcat approach. So what could I be missing as have spent hours googling around this and changing users, groups, permissions etc... as it must be a Tomcat, Geoserver or GeoWebCache setting preventing that //geoserver-blobstore folder being seen a writable. The folder is currently owner by root but I changed it to tomcat at one point but didn't seem to make a difference.
