Hi @Hassan_jalali Welcome to the community!
So lets back up a bit...
If you want to run APM server standalone ... then you do not use Fleet but you still need to load the integration .... Interesting I just help someone solve this here
But you do not use Fleet + Standalone APM Server
It is important to realize ... That Fleet and APM Integration are just Special Policies / Integration inside and Agent ... APM Integration is the the new APM Server
If you want to use Fleet then do Follow These Documents but this will install fleet on the host not in docker... then install the APM Integrations
And Seems like you want to run fleet in a container so then you install as docker (which I think is a bit harder) ... you would need to follow these directions to install
Yes sorry / confusing... harder than it should be
Take a look at these and then come back...
