When as a result, current container is directly assembled;S240 judges the state applied in previous container when analysis result is the second result
Whether current container is assembled in support, if support assembly current container, assembles current container.
In step S210, container can be docker containers.The order of assembling container can be in particular file format
Defined in (json, yarn), create, the order of assembling container.Configuration file can be that user is specified.Configuration file may include
Generate Container Name, container parameters etc..
In step S220, analysis result may include:Directly the first of assembly current container is as a result, need to judge
Whether the state applied in the previous container of current container supports the second result of assembly current container.
The realization method parsed to configuration file is for example:Parsing module reads json formats or the configuration of yarn formats
The content of file is converted to the collection of the call instruction of docker containers or docker API and program code segments according to file content
It closes, can be bash shell programs either python shell scripts or other programming languages.This script journey parsed
Ordered sets can be put into disk file (such as a.sh or a.py).Or it in order to reduce disk I/O expense, directly opens up
Go out one piece of core buffer, parsing content is directly placed into core buffer.
In step S230, when analysis result is the first result, for example, current container is first container, because should
It does not need to judge at this time so will not be restricted by previous container when assembling the container without other containers before container
Order, can directly assemble current container.For example, analysis result is startup (docker start) or the container of container
The order for stopping (docker stop), can be with executive device current container.
In step S240, each container in container group (container packet) has relation of interdependence, such as the web of containerization
Cluster, boot sequence should be database container, web application containers, load balancing container, and must be that database container is complete
