Centos6.5 create a private docker RepositoryDocker private Registry Installation Guide under centos 6.x Note: docker.yy.comThis is the domain name of the docker registry server, that is, the host address of your company's docker private server. Assume that the ip address is192.168.2.114Because the https SSL certificate cannot use an IP address, I can name it. registryThe server acts as the upstream server to process the final upload and download of docker images, using an official image. ngi

Match: The information required to fill in the request must be consistent with the CA setup information; Support: means the application information must be filled in; optional: means dispensable.Experimental environment: Requires two hosts, I here with Host a (centos6:ip for 172.17.250.83) to create a CA and to other hosts to provide CA services; host

Download the official OpenStack document for installation (Icehouse Juno Kilo), according to the official documentation, download two RPM packages, for example, I want to build OpenStack Icehouse on centos6.5, need two installation packages, EPEL-RELEASE-6.8-NOARCH.RPM source package, in one is rdo-release--icehouse-4-src.rpm opened under window. Check the configuration profile inside, there are Foreman.repo Puppetlabs.repo Rdo-release.repo find their corresponding, there is a epel-release-6.8-n

classified into public and private keys.Public Key: extracted and generated from the private key; can be made public to everyone;Private Key: It is created using tools and kept by the user. The private key must be kept confidential; Features: data encrypted with the public key can only be decrypted using the private key of the matching child; and vice versa;Purpose:Digital Signature: allows the recipient to confirm the sender's identity;Key Exchange: the sender encrypts a symmetric key with the

What's Token?Popularly speaking, token is a user's credential, need to take the correct user name/password to Keystone application to get. If users use username/password to access OpenStack API each time, it is easy to disclose user information, which poses a security risk. So OpenStack requires users to access their APIs before they need to get tokens, and then use token as their user credentials to access the OpenStack API. The origins of the four tokensD version, only the UUID type Toke
