我是这样使用的kafka-console-producer.sh：
kafka-console-producer.sh --bootstrap-server $BTSTRP --topic test --producer.config client.properties
它运行良好，没有警告或错误。在client.properties我有一些属性。示例文件的一部分：
security.protocol=SASL_SSL
sasl.mechanism=SCRAM-SHA-512
ssl.endpoint.identification.algorithm=
然后我想使用下面的命令来列出使用相同的 SCRAM 用户，client.properties因为它匹配这里的所有内容：
kafka-configs.sh --bootstrap-server $BTSTRP --command-config client.properties --describe --entity-type users
但它打印低于警告（不是完整输出）并且最终不起作用（只打印这些警告）：

# Build binary
FROM golang:1.17-alpine AS build-env
ADD . /app
WORKDIR /app
RUN env CGO_ENABLED=0 go build -ldflags="-s -w" -o myapp ./cmd/myapp/main.go
# Create image
FROM scratch
COPY --from=build-env /app/myapp /
ENTRYPOINT ["/myapp"]
由于 Golang 允许针对多种架构进行交叉编译（并且比在模拟环境中构建要快得多），所以我想做这样的事情：
# Build binary
FROM golang:1.17-alpine AS build-env
ADD . /app
WORKDIR /app
RUN env CGO_ENABLED=0 GOOS=linux GOARCH=386 go build -ldflags="-s -w" -o myapp_linux_i386 ./cmd/myapp/main.go # Linux 32bit
RUN env CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags="-s -w" -o myapp_linux_x86_64 ./cmd/myapp/main.go …首先，我已经看过这个线程，但它不相关并且有不同的问题。
我的 Kafka 属性文件中有以下设置片段：
ssl.keystore.type=PEM
ssl.keystore.key=/path/to/private.key
ssl.keystore.certificate.chain=/path/to/certificate.pem
ssl.truststore.type=PEM
ssl.truststore.certificates=/path/to/ca.pem
ssl.endpoint.identification.algorithm=
请注意，ssl.endpoint.identification.algorithm使用 是因为集群中的每个服务器都使用单服务器证书，因此我必须通过这种方式绕过 SSL 主机名验证。
