【问题描述】:
我正在这样启动操作系统:
oc cluster up --public-hostname=julio-oc.10.238.41.233.nip.io
我还有一个私有 github 存储库,配置了部署密钥,只有一个微不足道的 Dockerfile。
然后我将秘密添加如下:
oc secrets new-sshauth sleep-key-rsa --ssh-privatekey=/home/julio/.ssh/sleep-key_rsa
如果我尝试创建应用程序,它会失败:
> oc new-app --source-secret=sleep-key-rsa git@github-isl-01.ca.com:garju09/docker-sleep.git
error: Errors occurred while determining argument types:
git@github-isl-01.ca.com:garju09/docker-sleep.git as a Git repository URL: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
但如果我将密钥添加到 ssh 代理,它现在可以工作了:
> ssh-add ~/.ssh/sleep-key_rsa
Identity added: /home/julio/.ssh/sleep-key_rsa (/home/julio/.ssh/sleep-key_rsa)
> oc new-app --source-secret=sleep-key-rsa git@github-isl-01.ca.com:garju09/docker-sleep.git
--> Found Docker image 3fa8225 (2 weeks old) from Docker Hub for "centos:centos7"
* An image stream will be created as "centos:centos7" that will track the source image
* A Docker build using source code from git@github-isl-01.ca.com:garju09/docker-sleep.git will be created
* The resulting image will be pushed to image stream "docker-sleep:latest"
* Every time "centos:centos7" changes a new build will be triggered
* WARNING: this source repository may require credentials.

* This image will be deployed in deployment config "docker-sleep"
* The image does not expose any ports - if you want to load balance or send traffic to this component
you will need to create a service with 'expose dc/docker-sleep --port=[port]' later

为什么new-app没有使用我指定的--source-secret?
更新:
> oc version
oc v3.7.0+7ed6862
kubernetes v1.7.6+a08f5eeb62
features: Basic-Auth GSSAPI Kerberos SPNEGO
Server https://127.0.0.1:8443
openshift v3.7.0+7ed6862
kubernetes v1.7.6+a08f5eeb62
我的主要信息来源是以下博客:https://blog.openshift.com/private-git-repositories-part-2a-repository-ssh-keys/
请注意,密钥上没有密码,我尝试了各种其他排列,包括以下。唯一适用于项目创建的是ssh-add。奇怪的是,创建项目后,我可以清空ssh-agent 并且操作系统构建没有问题:
oc secrets new-sshauth sleep-key-rsa --ssh-privatekey=/home/julio/.ssh/sleep-key_rsa
oc secrets link builder sleep-key-rsa
oc new-app --source-secret=sleep-key-rsa https://github-isl-01.ca.com/garju09/docker-sleep.git
但上述方法不起作用,因为 https 需要在我们的部署中进行身份验证。
oc secrets new-sshauth sleep-key-rsa --ssh-privatekey=/home/julio/.ssh/sleep-key_rsa
oc secrets link builder sleep-key-rsa
oc new-app git@github-isl-01.ca.com:garju09/docker-sleep.git
也失败了。
更新 2: 我创建了一个 github 存储库来复制问题并显示我正在使用的脚本:https://github.com/julio-garcia-fc/docker-sleep
如果你克隆它并拥有 oc 3.7,你应该能够运行 oc.sh 并且你会看到它失败。
【问题讨论】:
-
您提到需要
ssh-add是因为oc new-app正在将源代码下载到您的本地计算机以运行算法来确定如何构建它。如果您尝试进行 docker 类型构建,请提供参数--strategy docker。如果您使用的是 S2I,请提供选项--strategy source并提供 S2I 构建器名称以与 repo 详细信息一起使用,即<s2i-builder-image>~<repository-url>。这样oc new-app不需要拉下 repo 来解决如何构建源代码。 -
请注意目前 (3.6/3.7) 在
oc new-app中存在一个错误,如果使用--strategy source并使用--image-stream作为 S2I 构建器名称,使用--code作为存储库 URL,它错误地仍在拉回购,并不必要地试图弄清楚如何构建。避免使用显式选项并使用<s2i-builder-image>~<repository-url>形式的命令。
