VM上的坞内没有互联网

Question

我是运行模式-红色模块的nodejs与码头-组成如下：

version: "3"
services:
    node-red:
        build: node-red/.
        container_name: mynodered
        network_mode: "host"
        volumes:
         - $PWD/data/node:/data
        ports:
         - "1880:1880"

我已将以下停靠文件放置在node-red文件夹中

FROM nodered/node-red-docker:v8
RUN npm i -S basic-auth bcryptjs body-parser cheerio clone cookie cookie-parser cors cron express express-session follow-redirects fs-extra fs.notify hash-sum i18next is-utf8 js-yaml json-stringify-safe jsonata media-typer memorystore mqtt multer mustache node-red-contrib-cloudera node-red-contrib-confluent node-red-contrib-ksql node-red-contrib-python-function node-red-contrib-rdkafka node-red-contrib-s3 node-red-node-email node-red-node-feedparser node-red-node-rbe node-red-node-twitter nopt oauth2orize on-headers passport passport-http-bearer passport-oauth2-client-password raw-body semver sentiment uglify-js when ws xml2js && npm i -D chromedriver grunt grunt-chmod grunt-cli grunt-concurrent grunt-contrib-clean grunt-contrib-compress grunt-contrib-concat grunt-contrib-copy grunt-contrib-jshint grunt-contrib-uglify grunt-contrib-watch grunt-jsonlint grunt-mocha-istanbul grunt-nodemon grunt-sass grunt-simple-mocha grunt-webdriver istanbul mocha should sinon supertest wdio-chromedriver-service wdio-mocha-framework wdio-spec-reporter webdriverio && npm i -O bcrypt

当我以如下方式从这个停靠文件构建映像时，它的工作精细

docker build --network host -t dvnode .

但是，当我使用坞-撰写时，它会产生以下错误：

docker-compose up

Answer 1

正如hardlib在评论中提到的，这实际上是DNS查找的问题，根据链接，我能够解决相同的issue.Thus，重申这些步骤以避免进一步的混淆：

1)查找与您的系统相关的DNS：

nmcli device show <interface-name> | grep IP4.DNS

其中接口名称是由ifconfig找到的名称。

2)编辑保存在docker.service中的/lib/systemd/system文件，并以下列方式替换ExecStart行并保存：

ExecStart=/usr/bin/dockerd --dns <dns-id> --dns <dns-id> -H fd://

其中dns-id是从上述步骤中找到的值。

3)重新启动服务

sudo systemctl daemon-reload
sudo systemctl restart docker
