如何通过命令行传递一个配置文件和pem密钥？

Question

我想在我的CICD服务器上运行Knife来上传食谱。

我运行的是临时从属目录，所以在默认情况下创建一个包含所有文件的静态目录是不可能的，也是很痛苦的(每次容器从属服务器运行时都要写出这个结构)。

我是否可以将knife.rb配置作为文本传递给刀具命令，也可以将pem文件作为args传递给它？

我正在尝试使用--config-option，但是Knife仍然需要一个配置文件：

knife status \
--config-option log_level=:info \
--config-option log_location=STDOUT \
--config-option node_name="myadminuser" \
--config-option client_key="admin.pem" \
--config-option chef_server_url="https://myserver.com/organizations/myorg"

获取错误：

Answer 1

由于刀子配置通常是一次性设置，因此不需要每次或动态配置它。

相反，您可以将knife configuration (knife.rb or client.rb)放在.chef directory in your chef repository (.chef/knife.rb)中

另外，由于配置是用ruby编写的，所以您可以在配置中使用环境变量。

如果您有多个刀配置，请使用knife-spork to switch between them

Answer 2

您可以尝试-创建(touch)一个虚拟的config.rb文件，然后使用--config-option传递所有选项。

示例：

touch config.rb; \
knife status \
--config config.rb
--config-option log_level=:info \
--config-option log_location=STDOUT \
--config-option node_name="myadminuser" \
--config-option client_key="admin.pem" \
--config-option chef_server_url="https://myserver.com/organizations/myorg"
