在Ubuntu中设置Google Cloud Managed VM时发生DockerDaemonConnectionError [英] DockerDaemonConnectionError when setting Google Cloud Managed VM in Ubuntu

问题描述

我试图根据本手册在Ubuntu中安装Google Cloud Managed VM： [1] ， [2]

我已经按照 Docker安装安装了Docker指导。
$ b 运行Docker： sudo docker -H tcp：//127.0.0.1：2376 -d

我已经根据 HTTPS Docker指南。

我的环境变量：

• DOCKER_HOST = tcp：//：2376


• DOCKER_TLS_VERIFY = 1


• DOCKER_CERT_PATH = / home / eyalev / ca

$ b

当我运行 gcloud预览应用程序安装托管-vms





我得到一个错误：

有没有我缺少的东西？

解决方案

我最终得到了 gcloud preview app setup-managed- vms 在ubuntu上工作。以下是我必须做的：






1. 获取docker 1.3.0，而不是1.3.1。 sudo apt-get install docker.io 在我的机器上安装了旧版本的docker，所以我必须先删除它。但 curl -sSL https://get.docker.com/ubuntu/ | sudo sh 安装版本1.3.1，这也不起作用。我在 https://get.docker.com/ubuntu/ 中重播了脚本中的每一行，但我必须更改最后一行 apt-get安装-y lxc-docker 到 apt-get install -y lxc-docker-1.3.0 官方文档提到应用程序引擎没有使用boot2docker 1.3.1，但我认为它们意味着它不能用于docker 1.3.1。
   

2. 我无法获得127.0.0.1作为我的主机名工作。创建ca和服务器证书时，必须使用 localhost 。
   

3. 我必须导出 DOCKER_HOST = tcp：// localhost：2376 （注意使用localhost ）以及 DOCKER_TLS_VERIFY = 1 和 DOCKER_CERT_PATH =<路径>

$ b $我将/ etc / default / docker中的DOCKER_OPTS设置为 - tlsverify --tlscacert =<路径> /ca.pem --tlscert =<路径> /服务器-cert.pem --tlskey =<路径> /server-key.pem -H = 0.0.0.0：2376



gcloud预览应用程序设置管理 - vms 现在可以使用，但我没有收到 gcloud预览应用程序运行为我的应用程序工作。




I'm trying to install Google Cloud Managed VM in Ubuntu according to this manuals: [1], [2]

I've installed Docker following the Docker installation guide.

Running Docker with: sudo docker -H tcp://127.0.0.1:2376 -d

I've created certificate keys according to the HTTPS Docker guide.

My environments variables:

• DOCKER_HOST=tcp://:2376
• DOCKER_TLS_VERIFY=1
• DOCKER_CERT_PATH=/home/eyalev/ca

When I run gcloud preview app setup-managed-vms

I get an error:

DOCKER_CERT_PATH and DOCKER_TLS_VERIFY are set correctly. If you are
using boot2docker, make sure you have run "$(boot2docker shellinit)"

Is there something I'm missing?

解决方案

I finally got gcloud preview app setup-managed-vms to work on ubuntu. Here's what I had to do:

1. get docker 1.3.0, not 1.3.1. sudo apt-get install docker.io installed and old version of docker on my machine, so I had to remove that first. But curl -sSL https://get.docker.com/ubuntu/ | sudo sh installs version 1.3.1, which also doesn't work. I replayed every line in the script at https://get.docker.com/ubuntu/ but I had to change the last line apt-get install -y lxc-docker to apt-get install -y lxc-docker-1.3.0 The official docs mention that app engine doesn't work with boot2docker 1.3.1, but I think they meant that it doesn't work with docker 1.3.1.

2. I couldn't get 127.0.0.1 to work as my host name. I had to use localhost when creating the ca and server certificates.

3. I had to export DOCKER_HOST=tcp://localhost:2376 (note the use of localhost) along with DOCKER_TLS_VERIFY=1 and DOCKER_CERT_PATH=<path>

4. I set DOCKER_OPTS in /etc/default/docker to "--tlsverify --tlscacert=<path>/ca.pem --tlscert=<path>/server-cert.pem --tlskey=<path>/server-key.pem -H=0.0.0.0:2376"

gcloud preview app setup-managed-vms works now, but I haven't gotten gcloud preview app run for my go app to work yet.
