Angular-CLI代理不能在Docker中工作
我有一个docker-compose文件，包含我需要的所有项目。
这个docker-compose有一个nginx服务器，mysql，phpmyadmin和php。 在它的顶部，我最近添加了一个angular形容器。 一切工作正常，如果我去localhost：4200，我在angular应用程序，如果我去本地主机：80，我在Laravel后端。
现在我需要对我的后端API做一个简单的经典请求。 我build立了一个代理angular度看起来像这样：
{ "/api/*": { "target":"http://localhost:80", "secure":false, "changeOrigin":true, "pathRewrite": {"^/api" : ""}, "logLevel":"debug" } } 这是我根据这个主题复制的configuration。 但是，当我尝试拨打电话时，Chrome浏览器正在说http：// localhost：4200 / api / test不存在（错误404），这是正常的。 另一方面，angular度服务器说
HPM] Error occurred while trying to proxy request /test from localhost:4200 to http://localhost:80 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)
我猜这是来自docker，但我不知道如何解决这个问题。

这里是PHP和Angular的Dockerfiles：
PHP：
FROM php:7-fpm RUN docker-php-ext-install pdo pdo_mysql WORKDIR /var/www
Angular：
#Latest Node FROM node #Creating working folder RUN mkdir -p /usr/src/app #Update pwd WORKDIR /usr/src/app #Run npm RUN npm install EXPOSE 4200 CMD ["npm", "start"]
package.json：
{ "name": "client", "version": "0.0.0", "license": "MIT", "scripts": { "ng": "ng", "start": "ng serve -H 0.0.0.0 --proxy-config proxy.config.json", "build": "ng build", "test": "ng test", "lint": "ng lint", "e2e": "ng e2e" }, "private": true, "dependencies": { "@angular/animations": "^4.2.4", "@angular/common": "^4.2.4", "@angular/compiler": "^4.2.4", "@angular/core": "^4.2.4", "@angular/forms": "^4.2.4", "@angular/http": "^4.2.4", "@angular/platform-browser": "^4.2.4", "@angular/platform-browser-dynamic": "^4.2.4", "@angular/router": "^4.2.4", "core-js": "^2.4.1", "rxjs": "^5.4.2", "zone.js": "^0.8.14" }, "devDependencies": { "@angular/cli": "1.3.2", "@angular/compiler-cli": "^4.2.4", "@angular/language-service": "^4.2.4", "@types/jasmine": "~2.5.53", "@types/jasminewd2": "~2.0.2", "@types/node": "~6.0.60", "codelyzer": "~3.1.1", "jasmine-core": "~2.6.2", "jasmine-spec-reporter": "~4.1.0", "karma": "~1.7.0", "karma-chrome-launcher": "~2.1.1", "karma-cli": "~1.0.1", "karma-coverage-istanbul-reporter": "^1.2.1", "karma-jasmine": "~1.1.0", "karma-jasmine-html-reporter": "^0.2.2", "protractor": "~5.1.2", "ts-node": "~3.2.0", "tslint": "~5.3.2", "typescript": "~2.3.3" } }
你的问题是，你没有复制package.json并且当没有package.json时，npm install不会执行任何操作
改变你的angular度文件到下面
#Latest Node FROM node #Creating working folder RUN mkdir -p /usr/src/app -p /usr/src/node_modules ENV NODE_PATH=/usr/src/node_modules WORKDIR /usr/src/app COPY package.json ./package.json RUN npm install EXPOSE 4200 CMD ["npm", "start"]
这会将您的node_nodules安装在$NODE_PATH ，该文件是/usr/src/node_modules
改变你的angular度服务在撰写如下
angular: restart: always build: /docker/angular container_name: angular volumes: - /projects/angular:/usr/src/app/ ports: - "4200:4200"
package.json的额外条目是不需要的。 现在，即使您要从本地文件夹挂载覆盖/usr/src/app/node_modules ，但我们已经将节点模块更改为在/usr/src/node_modules
我通过从docker中删除Angular并用一个简单的npm start手动运行来解决这个问题。
