怎么在k8s环境下的rabbitmq安装社区版插件:rabbitmq_delayed_message_exchange
在你的rabbit-value.yaml中加入以下行，然后使用helm重新安装（最好把pvc也删了重新安装（如果你的密码变化了的话） 减少出错概率）
## @param plugins List of default plugins to enable (should only be altered to remove defaults; for additional plugins use `extraPlugins`)
##
plugins: "rabbitmq_management rabbitmq_peer_discovery_k8s"
## @param queue_master_locator Changes the queue_master_locator setting in the rabbitmq config file
##
queue_master_locator: min-masters
## @param communityPlugins List of Community plugins (URLs) to be downloaded during container initialization
## Combine it with extraPlugins to also enable them.
##
communityPlugins: "https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/v4.0.2/rabbitmq_delayed_message_exchange-4.0.2.ez"
## @param extraPlugins Extra plugins to enable (single string containing a space-separated list)
## Use this instead of `plugins` to add new plugins
##
extraPlugins: "rabbitmq_auth_backend_ldap rabbitmq_delayed_message_exchange"
## Clustering settings
##
helm install my-rabbit-dev bitnami/rabbitmq -f rabbit-value.yaml -n yournamespace
过程中踩坑
1 rabbitmq_delayed_message_exchange是社区版的plugin 所以要在communityPlugins加入，而且这里要加入的是能直接下载的链接
communityPlugins: "https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/v4.0.2/rabbitmq_delayed_message_exchange-4.0.2.ez"
如果不是下载地址而是网页链接 我安装过程中没报错 探针也过了，但是可以去容器的/opt/bitnami/rabbitmq/plugins
目录下查看，根本没有这个插件。
2 我一开始是把他当正常插件使用了
只写了extraPlugins，没在communityPlugins写内容，会报错：
cannot_read_enabled_plugins_file,"/opt/bitnami/rabbitmq/etc/rabbitmq/enabled_plugins
{1,erl_parse,"bad term"}},{rabbit,start,[normal,[]]}}
readiness probe failed: % total % received % xferd average speed time time time current dload upload total spent left speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 curl: (7) failed to connect to 127.0.0.1 port 15672 after 0 ms: couldn't connect to server
等一些列奇怪的错误，原因应该就是rabbitmq_delayed_message_exchange 找不到 也没在communityPlugins那里添加，
communityPlugins: ""
## @param extraPlugins Extra plugins to enable (single string containing a space-separated list)
## Use this instead of `plugins` to add new plugins
##
extraPlugins: "rabbitmq_auth_backend_ldap rabbitmq_delayed_message_exchange"
要在communityPlugins那里加上下载地址 同时在extraPlugins 加上 以启用他 其实仔细读注释 人家早就说了 Combine it with extraPlugins to also enable them.！
## @param communityPlugins List of Community plugins (URLs) to be downloaded during container initialization
## Combine it with extraPlugins to also enable them.
