3月20日，Istio 1.1版本正式发布，我们已在《全方位解读 | Istio v1.1正式发布》一文中为大家进行了简单介绍。本文将给大家带来详细的部署过程详解，需要说明的是，本文针对单集群安装部署，多集群安装部署会在后续文章中详细说明。前提条件正确安装配置Kubernetes集群CentOS Linux release 7.5.1804安装下载istio 1.1版本[root@vm157 ~]# wget https://github.com/istio/istio/releases/download/1.1.1/istio-1.1.1-linux.tar.gz ……2019-03-26 09:39:06 (483 KB/s) -
