我不知道在哪里还可以把所有的例子,我已经看到我有很多复制,仍然无法让它工作.连接器将无法安装和状态空密码.我已经验证了每一步,不能让它工作.这里是我采取的步骤.

容器

FROM strimzi/kafka:0.16.1-kafka-2.4.0
USER root:root
RUN mkdir -p /opt/kafka/plugins/debezium
COPY ./debezium-connector-mysql/ /opt/kafka/plugins/debezium/
USER 1001

字符串
接下来,我将创建用于mySQL的secret。

cat <<EOF | kubectl apply -n kafka-cloud -f - 
apiVersion: v1
kind: Secret
metadata:
  name: mysql-auth
type: Opaque
stringData:
  mysql-auth.properties: |-
    username: root
    password: supersecret
EOF


我知道了

% kubectl -n kafka-cloud get secrets | grep mysql-auth
mysql-auth                                     Opaque                                1      14m


仔细检查以确保用户和密码不为空,因为连接器状态中存在错误。

% kubectl -n kafka-cloud get secret mysql-auth -o yaml

apiVersion: v1
data:
  mysql-auth.properties: dXNlcm5hbWU6IHJvb3QKcGFzc3dvcmQ6IHN1cGVyc2VjcmV0
kind: Secret
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"v1","kind":"Secret","metadata":{"annotations":{},"name":"mysql-auth","namespace":"kafka-cloud"},"stringData":{"mysql-auth.properties":"username: root\npassword: supersecret"},"type":"Opaque"}

添加连接集群

cat <<EOF | kubectl apply -n kafka-cloud -f -
apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaConnect
metadata:
  name: my-connect-cluster
  annotations:
#  # use-connector-resources configures this KafkaConnect

  externalConfiguration:
    volumes:

        secret:
          secretName: mysql-auth
EOF

添加连接器

cat <<EOF | kubectl apply -n kafka-cloud -f -

kind: KafkaConnector
metadata:
    name: mysql-test-connector
    labels:

        database.password: "${file:/opt/kafka/external-configuration/mysql-auth-config/mysql-auth.properties:password}"

        key.converter: "org.apache.kafka.connect.storage.StringConverter"
        value.converter: "org.apache.kafka.connect.storage.StringConverter"
EOF

错误

不管我怎么尝试得到这个错误。我不知道我错过了什么。我知道这是一个简单的配置,但我不能弄清楚。我卡住了。
