在docker compose中使用mosquitto-go-auth错误

Question

我已经在 ubuntu 虚拟系统上设置了 mosquitto-go-auth。我开始尝试将我创建的系统转移到docker compose。 我从 Ubuntu 系统复制了我的文件，复制了配置。

mosquitto.conf：

persistence true
persistence_location /var/lib/mosquitto/

# log info:
log_dest file /mosquitto/log/mosquitto.log

# auth:
allow_anonymous false
listener 1883
auth_plugin /mosquitto/config/go-auth.so
auth_opt_log_level debug
require_certificate false

# postgress options:
auth_opt_backends postgres
auth_opt_pg_host postgres
auth_opt_pg_port 5432
auth_opt_pg_dbname API
auth_opt_pg_user mqtt_user
auth_opt_pg_password mqtt_pass

# hash options:
auth_opt_pg_hasher bcrypt
auth_opt_pg_hasher_salt_size 16           # salt bytes length


# ssl
auth_opt_pg_sslmode disable

# auth options
auth_opt_pg_connect_tries 5
auth_opt_pg_userquery select password from MqttUser where login = $1 limit 1
auth_opt_pg_superquery select count(*) from test_user where username = $1 and is_admin = true

尝试启动 docker compose up 时。 我收到此错误：

Config loaded from /mosquitto/config/mosquitto.conf.
Loading plugin: /mosquitto/config/go-auth.so
Error: Unable to load auth plugin "/mosquitto/config/go-auth.so".
Load error: Error relocating /mosquitto/config/go-auth.so: __fprintf_chk: symbol not found

我认为原因是缺少安装golang。但我不知道如何在我的 docker compose 中安装它。

请帮助我在我的 docker compose 中设置 mosquitto-go-auth 的使用

Answer 1

这里最好的解决方案是将 eclipse mosquitto 容器替换为 mosquitto-go-auth 插件项目中的容器。

在基于 glibc 的平台（例如 Ubuntu）上构建的预构建和任何二进制文件不太可能在基于 Muscl Alpine 的 eclipse mosquitto 容器上运行。

请注意，更新 Docker-compose.yml 中卷的安装位置时，配置文件的某些路径将会更改。
