干货 | 京东云Kubernetes集群+Traefik实战

由 放肆的年华 提交于 2021-02-16 16:41:03
摘要 Traefik支持丰富的annotations配置，可配置众多出色的特性，例如：自动熔断、负载均衡策略、黑名单、白名单。所以 Traefik对于微服务来说简直就是一神器。 利用Traefik，并结合京东云Kubernetes集群及其他云服务（RDS，NAS，OSS，块存储等）， 可快速构建弹性扩展的微服务集群。 Traefik是一个为了让部署微服务更加便捷而诞生的现代HTTP反向代理、负载均衡工具。它支持多种后台（Kubernetes，Docker，Swarm，Marathon，Mesos，Consul，Etcd，Zookeeper等）。 本文大致步骤如下： Kubernetes权限配置（RBAC）； Traefik部署； 创建三个实例服务； 生成Ingress规则，并通过PATH测试通过Traefik访问各个服务； Traefik配置域名及TLS证书，并实现HTTP重定向到HTTS。 本文部署Traefik使用到的Yaml文件均基于Traefik官方实例，并为适配京东云Kubernetes集群做了相关修改： https://github.com/containous/traefik/tree/master/examples/k8s 基本概念 1 Ingress边界路由 虽然Kubernetes集群内部署的pod、server都有自己的IP，但是却无法提供外网访问

Deploying Docker to AWS Elastic Beanstalk — how to forward port to host? (port binding)

由 旧街凉风 提交于 2021-02-16 14:56:46
问题 I have a project set up with CircleCI that I am using to auto-deploy to Elastic Beanstalk. My EBS environment is a single container, auto-scaling, web environment. I am trying to run a service that listens on raw socket port 8080. My Dockerfile: FROM golang:1.4.2 ... EXPOSE 8080 My Dockerrun.aws.json.template: { "AWSEBDockerrunVersion": "1", "Authentication": { "Bucket": "<bucket>", "Key": "<key>" }, "Image": { "Name": "project/hello:<TAG>", "Update": "true" }, "Ports": [ { "ContainerPort":

Can't connect to WSL2 localhost server from WSL2 docker container

由 时间秒杀一切 提交于 2021-02-16 13:20:28
问题 I am running a simple web server on https://0.0.0.0:4000 (accessible also as https://local.phx-cd.shoepping.at:4000 with mapping to 127.0.0.1 in Ubuntu hosts file) on my WSL2 Ubuntu. I can connect to it from both Ubuntu and Windows host - so far so good. But additionally, in my Docker for Win with WSL2 integration, I run a selenium chrome container which is connecting and testing stuff on that web server (using bridge), but it can't connect to it! I connected to the container and tried to

docker-compose: reinitializing MySQL db every time

由 牧云@^-^@ 提交于 2021-02-16 09:23:07
问题 We have a Rails app with MySQL as DB. The db part of docker-compose.yml looks like db: image: mysql env_file: - ma.env volumes: - ./dump-db:/docker-entrypoint-initdb.d - ./my.cnf:/etc/mysql/my.cnf restart: always ports: - "3306:3306" environment: - MYSQL_HOST= and under ./dump-db folder there actually is an sql-dump of our db. Problem is, we need to have that exact dump loaded each and every time docker-compose up is run. MySQL docker image works in such a way, that it stores it's data on

Migrating existing containers from Hyper-V to WSL2 technology

由 不羁的心 提交于 2021-02-16 04:37:08
问题 After DockerCon 2020, I enthusiastically downloaded Windows 10 2004 and tried to upgrade Docker Desktop to WSL 2 containers and experiment. I had a few containers, in particular a couple of databases along with their data stored within volumes. Postgres and MS SQL Server in the case. I wouldn't like to lose the data, though it's not critical. I used Docker volumes rather than OS mounts because I have repeatedly seen that using Windows mounts for database data storage is not recommended. When
