[GeoNode-users] GWC doesn't work normaly for GeoExt client on docker Geonode 2.10 master

[Dejan Samardzic]

Dear Geonode community,

We have made docker Gonode 2.10 master branch installation on Ubuntu 18.04 by Alessio's guide:

https://docs.google.com/document/d/1S0ac9IR9IW9tUjMu7JETPLUjnfQ6P87m1PKNko8IPWY/edit

after that we have configure GeoWebCache:
1) We have configure Caching to external postgresql database:
Tile caching - Disk quota....Enable disk Quota ....Maximum tile cache size 50GiB
Disk quota check frequency:600s
Disk quota store type....External database
Target database type....PostgreSQL
JDBC data source...GeoServer managed connection pool
JDBC Driver class name.....org.postgresql.Driver
JDBC connection URL.....jdbc:postgresql://db:5432/geonode
User name.....geonode
Password.....****
Validation query.....select 1

2) Define path for cache
>From geoserver container:
mkdir /var/cache/geoserver
chmod -R 777 geoserver
vi /usr/local/tomcat/webapps/geoserver/WEB-INF/web.xml
insert :
<context-param>
       <param-name>GEOWEBCACHE_CACHE_DIR</param-name>
       <param-value>/var/cache/geoserver/</param-value>
</context-param>

Now, GeoWebCache doesn't work (geowebcache-cache-result is always MISS and system is not generating png files in GEOWEBCACHE_CACHE_DIR).
We have to remove/add that specitic layer in Geoserver->Tile Caching->Tile Layers. After that, GWC start working normally (geowebcache-cache-result is HIT and system start generating png files in GEOWEBCACHE_CACHE_DIR).
Let me underline that before and after this remove/add actions, url on browser's Developer Tool has the same structure like:
http://testgis.cedis.me/geoserver/ows?access_token=pNPeKSZxG60GgtYcUJ97RCMKKGuIXm&LAYERS=geonode%3Anovi_r5_Grbalj_3_10kV_izmjenjen&FORMAT=image%2Fpng&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&TILED=true&SRS=EPSG%3A3857&BBOX=2088259.6124603,5217897.2981329,2088565.3605734,5218203.046246&WIDTH=256&HEIGHT=256
