Andrew Onischuk commented on AMBARI-3556:
-----------------------------------------
These changes can be described by the lines below:
{code}
- def __init__(self):
+ def __init__(self, basedir=None, params=None):
+ """
+ @param basedir: basedir/files, basedir/templates are the places where
templates / static files
+ are looked up
+ @param params: configurations dictionary (this will be accessible in the
templates)
+ """
{code}
So now our code will just like this:
{code}
def main():
# this we should pass as parameter
basedir = "/HDP/Stack2.0.6/HBase/"
# this will be parsed from json
config = {
"hadoop_base": "/opt/hadoop",
"hdfs_path": "/home/hduser/hdfs",
"jobtrackerport": "8021",
"replication": "3",
"hdfsport": "8020",
"slaves": ["hadoop-02","hadoop-03","hadoop-04"],
"master": "hadoop-01",
"version": "0.20.203.0",
"java_home": "/usr/jdk"
}
with Environment(basedir, config) as env:
# ...
File("/lol1.txt",
owner = "root",
group = "root",
content = Template("lol1.txt.j2"))
# ...
File("/a/b/file.txt",
owner = "root",
group = "root",
content = StaticFile("some1.txt"))
# ...
env.run()
{code}
{code}
basedir
files
some1.txt
templates
lol1.txt.j2
any_location
script.py
{code}
> Resource management. Rewrite Templates and Static Files to declarative rather
> than cookbook-oriented

> Key: AMBARI-3556
> URL: https://issues.apache.org/jira/browse/AMBARI-3556
> Project: Ambari
> Issue Type: Bug
> Reporter: Andrew Onischuk
> Assignee: Andrew Onischuk
> Fix For: 1.5.0
>
>
> 1) Since Kokki should be used with kitchen and cookbooks. Templates are not
> working then we use declative form. This can be fixed by replacing the
> location of cookbook with our custom param passed to the enviroment.
> 2) Also Here we should change the way variables are sent to templating
> engine. Since we will be getting variables from json configurations files and
> then parsing it into variable, probaby a dictionary of dictionaries. We
> should not use any files with configurations (like it is done in Kokki), but
> just pass the dictionary with the configuration params to the enviroment,
> which should handle it.
