ubuntu - 游牧模板 : Folder is created instead of file

Question

为什么在检查容器时 test.cnf 是目录而不是基于模板节的文件，请检查一下

  config {
    image = "percona/percona-xtradb-cluster:5.7"
    volumes = ["/tmp/new.conf:/etc/mysql/test.conf"]

    port_map {
      db = 3306
      gc = 4567
      ss = 4444
      ist = 4568
    }
  }

  template {
    data = <<EOH
      binlog_format=ROW
      default_storage_engine=InnoDB
      !include /etc/mysql/node.cnf
    EOH
    destination   = "/tmp/new.conf"
  }

有解决方案是使用mounts而不是 volumes .
https://www.nomadproject.io/docs/drivers/docker/#mounts

这是 Docker 文档的摘录。 Nomad 必须遵循该规范才能与 Docker 一起工作。

The type of mount, can be either volume, bind, tmpfs, or npipe.
Defaults to volume if no type is specified.
volume: mounts a managed volume into the container.
bind: bind-mounts a directory or file from the host into the container.
tmpfs: mount a tmpfs in the container.
npipe: mounts named pipe from the host into the container (Windows containers only).

由于 bind挂载类型允许您将文件从主机绑定(bind)到容器我建议您 use the bind example from the documentation .
