Updating configs

[alexa22013]

Hi,
Is there anyway to update emqx config when using bootstrapconfig https://github.com/emqx/emqx-operator/blob/main/config/samples/emqx/v2alpha1/emqx-full.yaml. Updating using a config file apart from using the dashboard to change configs?

Thanks.

Sorry, The bootstrap config can only be set at creation time or modified via the dashboard, there is no other way to do this at the moment.
This is because the bootstrap conf is mounted to emqx/emqx.conf, and the configuration modified during emqx runtime is stored in the data directory, which is merged with the etc directory once, and the data directory takes precedence over the etc directory, so even if we allow the bootstrap config to be modified after deployment, it will not necessarily take effect.

anyway to use a config reloader to updade the configs?

Will updating the cluster-override.conf file directly change the emqx config?

hey @zhongwencool Any ideas ?

Suggestion: Don't modify data/*-override.conf manually.

Description of how the configuration file is loaded:

1. Configuration priority: emqx.conf < ENV < cluster-overrride.conf
2. The changes to the configuration via Dashboard will go into cluster-override.conf
3. Before node starts, cluster-override.conf will be copied from the core node in the cluster to this node.

So if you modify cluster-override.conf manually, some changes may be overwritten by emqx.

So what exacly happens when cluster-override.conf file is modified by dashboard changes? Because when I change the file manually I see no changes reflected on the cluster or dashboard

Sorry for delay, maybe need restart EMQX application after update data/cluster-override.conf ? @zhongwencool

Need

1. stop emqx cluster
2. modify data/cluster-override.conf
3. start emqx cluster
