我需要编写一个使用我定义的任何不同作业的查询.

{job="traefik" OR job="cadvisor" OR job="prometheus"}

是否可以编写逻辑二进制运算符？

有时，当我运行我的剧本时，它会引发下一次失败：

我在集群上安装了spark,我也有马拉松,两者都在8080端口,如何更改spark-ui默认端口？

我已经在 AWS 上安装了 spark。当我尝试在 AWS 上执行时，它可以工作，但 spark 不起作用，当我检查 sparkMaster 日志时，我看到以下内容：

Spark Command: /usr/lib/jvm/java-8-oracle/jre/bin/java -cp /home/ubuntu/spark/conf/:/home/ubuntu/spark/jars/* -Xmx1g org.apache.spark$
========================================

我已经配置了下一个Dockerfile,它工作正常:

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD farr-api-0.1.0.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]

现在我想运行相同但使用docker-compose,所以我尝试使用相同的sintaxys,这是我的docker-compose.yml:

码头工人,compose.yml:

jar:
  image: frolvlad/alpine-oraclejdk8:slim
  volumes:
    - /tmp
  add: "farr-api-0.1.0.jar" "app.jar"
  command: sh -c 'touch /app.jar'
  environment:
    JAVA_OPTS=""
  entrypoint: [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]

它抛出下一个失败:

ERROR: yaml.parser.ParserError: while parsing a block mapping
  in "./docker-compose.yml", line 2, column 3
expected <block end>, but found '<scalar>'
  in "./docker-compose.yml", line 5, column 29

我认为这可能是sintax问题 …

我尝试在同一个文件中插入 2 个 ansible 块，但 Ansible 用第二个块替换了第一个块。

如果我插入接下来的 2 个块：

- name: Setup java environment
  blockinfile:
    dest: /home/{{ user }}/.bashrc
    block: |
      #Java path# 
      JAVA_HOME={{ java_home }}/

- name: Setup hadoop environment
  blockinfile:
    dest: /home/{{ user }}/.bashrc
    block: |
      #Hadooppath# 
      HADOOP_HOME={{ hadoop_home }}/

只有第二个块会在文件中，因为它替换了第一个块。

我正在尝试使用Traefik作为Ingress控制器在Nginx示例上配置基本身份验证.

我只是"mypasswd"在Kubernetes 的秘密上创造了秘密.

这是我正在使用的Ingress:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginxingress
  annotations:
    ingress.kubernetes.io/auth-type: basic
    ingress.kubernetes.io/auth-realm: traefik
    ingress.kubernetes.io/auth-secret: mypasswd
spec:
  rules:
  - host: nginx.mycompany.com
    http:
      paths:
      - path: /
        backend:
          serviceName: nginxservice
          servicePort: 80

我检查了Traefik仪表板,看来,如果我访问nginx.mycompany.com,我可以检查Nginx网页,但没有基本身份验证.

这是我的nginx部署:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80

Nginx服务:

apiVersion: v1
kind: Service
metadata:
  labels:
    name: nginxservice
  name: nginxservice
spec:
  ports:

我正在尝试将 Grafana 仪表板的导入复制到 Grafana。

我正在使用下一个模块：

- name: Export dashboard
  grafana_dashboard:
    grafana_url: "http://{{ inventory_hostname }}:3000"
    grafana_user: "user"
    grafana_password: "password"
    org_id: "1"
    state: present
    slug: "node-exporter"
    overwrite: yes
    path: "/tmp/test/node_exporter.json"

我在本地计算机和远程计算机中都有node_exporter.json。但是当我运行 ansible playbook 时，它会抛出下一个错误：

fatal: [172.16.8.231]: FAILED! => {"changed": false, "msg": "error : Unable to create the new dashboard node-exporter-test : 404 - {'body': '{\"message\":\"Dashboard not found\",\"status\":\"not-found\"}', 'status': 404, 'content-length': '54', 'url': 'http://172.16.8.231:3000/api/dashboards/db', 'msg': 'HTTP Error 404: Not Found', 'connection': 'close', 'date': 'Wed, 10 Apr 2019 14:52:58 GMT', 'content-type': 'application/json'}."}

它抛出该错误dashboard …

我想将Java中手动定义的字符串压缩为7z。然后我可以将其转换为 base64。我发现很多例子将文件压缩到 7z 然后保存到新文件中。

我只是尝试下一个代码，它正确地获取文件并压缩它：

private static void addToArchiveCompression(SevenZOutputFile out, File file, String dir) throws IOException {
        String name = dir + File.separator + file.getName();
        if (file.isFile()){
            SevenZArchiveEntry entry = out.createArchiveEntry(file, name);
            out.putArchiveEntry(entry);

            FileInputStream in = new FileInputStream(file);
            byte[] b = new byte[1024];
            int count = 0;
            while ((count = in.read(b)) > 0) {
                out.write(b, 0, count);
            }
            out.closeArchiveEntry();

        } else if (file.isDirectory()) {
            File[] children = file.listFiles();
            if (children != null){
                for (File child : children){
                    addToArchiveCompression(out, child, name); …

我使用默认 CentOS 7 AMI 创建实例。该 AMI 自动创建一个卷并附加到实例。是否可以使用 terraform 读取该卷 ID？我使用以下代码创建实例：

resource "aws_instance" "DCOS-master3" {
    ami = "${var.aws_centos_ami}"
    availability_zone = "eu-west-1b"
    instance_type = "t2.medium"
    key_name = "${var.aws_key_name}"
    security_groups = ["${aws_security_group.bastion.id}"]
    associate_public_ip_address = true
    private_ip = "10.0.0.13"
    source_dest_check = false
    subnet_id = "${aws_subnet.eu-west-1b-public.id}"

    tags {
            Name = "master3"
        }
}
