问题 I have a very similar question as this one. I do have an Angular application that collects data which are then processed via a REST Api. I can happily dockerize both applications and they run fine locally, however, when I try deploy them to make them accessible from "everywhere" I can only reach the front end, but the connection to REST Api is not functional. Inside my Angular app, I have a file baseurl.ts . That just contains: export const baseURL = 'http://localhost:3000/'; I make the

Docker搭建私有仓库（registry与Harbor）

阅读更多关于 Docker搭建私有仓库（registry与Harbor）

随着docker使用的镜像越来越多，就需要有一个保存镜像的地方，这就是仓库。目前常用的两种仓库：公共仓库和私有仓库。最方便的就是使用公共仓库上传和下载，下载公共仓库的镜像是不需要注册的，但是上传时，是需要注册的。私有仓库最常用的就是registry、Harbor两种，那接下来详细介绍如何创建私有仓库。一、搭建registry私有仓库 1）案例描述两台docker服务器，dockerA创建registry私有仓库，dockerB用于测试！ 2）案例实例（1）DockerA服务器的操作 [root@dockerA ~]# docker pull registry:2 //下载registry:2的镜像 [root@dockerA ~]# docker run -itd --name registry --restart=always -p 5000:5000 -v /registry:/var/lib/registry registry:2 //创建一个registry容器来运行registry服务； //-p：端口映射（前面是宿主机端口：后面是容器暴露的端口）； //-v：挂载目录（前面是宿主机的目录：后面的是容器的目录）自动创建宿主机的目录； //--restart=always：随docker服务的启动而启动！ [root@dockerA ~]# docker ps /

“Remove” a VOLUME in a Dockerfile

阅读更多关于 “Remove” a VOLUME in a Dockerfile

问题 I have a Dockerfile extending FROM an image that declares a VOLUME . Is there a way to overwrite the VOLUME directive in such a way, that it "removes" the VOLUME ? 回答1: No. The only way to do so, is if you clone Dockerfile of the image you use as base one (the one in FROM ) and remove the VOLUME directive manually. Then build it and use in your FROM as base one. 回答2: There are cases when you can not modify the original Dockerfile - in my case an image from production. The only chance is to
