Unable to read from Slave Pod about mongo-k8s-sidecar HOT 3 OPEN

I think I found a workaround. I think by default the read is not enabled on the secondaries. So I went to the mongo shell for each of mongo-1 and mongo-2 and ran this command

rs.slaveOk()

That solved the problem. Now all my primaries and secondaries are working great. I tested, by inserting a document in primary and reading it from secondaries.

Hope this helps.
Thanks,

I am also getting similar error. The primary (master) is working great. But the 2 secondaries (slaves) are not. Here is what I get after I bash to mongo-1 or mongo-2 (the secondaries):

rs0:SECONDARY> show dbs

But, when I do it on mongo-0 (primary) it shows the databases:

rs0:PRIMARY> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB

I checked rs.status() on each one of them and it looks correct to me. The "me" field has the respective :<port_number> and the "ismaster" and "secondary" fields all look correct. For the slave, I can see that the "primary" also got assigned correctly with the :<port_number> of the primary mongo instance.

It will be great to have a solution to this problem.

Hello, I'm facing the same issue here.

I did rs.slaveOk() on each pod, however, that only worked for a while, and after that, the error came back.

Any ideas how we can make this a permanent change?
