oozappa 0.8.5

0.8.5

Adding new feature, modify Jobsets sort order on jobsets page.

Adding new feature, modify a Job data on environ page.

Improve Fabric task’s behavior better when failed.

You need db migration if you use 0.8.4 or below.

Download zip archive from https://github.com/tsuyukimakoto/oozappa/raw/master/migration/to_0.8.5.zip

$ unzip to_0.8.5.zip && cd oozappa_to_0_8_5

If you have not alembic installed. You need install it using pip or any way you like.
Open alembic.ini and modify sqlalchemy.url to indicate your own oozappa's db. then

$ alembic upgrade 1e26220da128

0.8.4

Jobset runs exclusively from webui.

0.8.3

A zappa command added and removed oozappa.create_environment module.

0.8.2

Oozappa finds tasks from imported modules, not recursive.

Environment

Environment is a category that has fibfile directory and vars.py .

A problem about fabric with large project is, too many fabric tasks and complicated task orders.

So you should separate fabfile into domain category. That is Environment.

Job

Job is like a normal fabric execution command.

note:

fab task1 task2 is a job.

Jobset

Jobset is oozappa operation unit.

Jobset can contain multiple job, even extend over environments.

vars

common and each environment’s vars.py might have oozappa.config.OozappaSetting instance named settings. OozappaSetting is dict like object.

common.vars.setting is updated by executed environment’s vars.setting , so you can set base configuration to common.vars.setting and environment’s one overwrite it.

Check printsetting task on staging environment.

You can run fabric task within environment directory as usual.

$ cd sample/ops/staging
$ fab printsetting
{'instance_type': 't1.micro', 'domain': 'localhost', 'sample_template_vars': {'sample_a': {'key_a_2': "a's 2 value from common.vars", 'key_a_1': "a's 1 value from stging.vars"}}, 'email': 'mtsuyuki at gmail.com'}

See common/vars.py and staging/vars.py .

templates

Same as vars, oozappa.fabrictools.upload_template search template. upload_template is almost same as fabric.contrib.files.upload_template . oozappa’s upload_template doesn’t accept use_jinja, because oozappa’s upload_template pass use_jinja=True to fabric.contrib.files.upload_template.

Jinja2 has inheritance template system and search template from multipul paths. fabric’s upload_template accept only one template_dir string not list. fabric doesn’t assume multiplu environment , so it’s reasonable. Because of this, oozappa’s upload_template search template path is limited only one template_dir that found filename. It mean that you can’t store child template and parent template separately.

common/functions

Call oozappa.config.procure_common_functions () and add commons/functions directory to sys.path for convinient to using on multiple fabric environment.

Rapid execution

Modify Run fabric in raw’s left hand side input to staging and click run_tasks. You can see what tasks exists.

Then input ls ps to right hand side input and click run_tasks .

That’s it.

Better way using sample

register environment to db.

• Click environment button via top menu.

• Add new Environment

  • name: constructiton

  • sort_order: 1

  • execute_path: constructiton

• Add 3 more.

create job in each environments.

• Click environment you created

• Create new Job.

  • Click task from Possible tasks in order

create jobset

• Click jobset button via top menu.

• Click jobs you’d like to execute once.

run jobset

• Click navigation button or jobset button via top menu.

• Click jobset you’d like to execute.

• Click run jobset button.

• Running log displays Running log.

• Reload page when jobset done. or Go to top(via navigation button)

  • You see Execute Logs and show raw log when you click success (or fail).

Create common directory

Change directory your own oozappa.

$ mkdir devops
$ cd devops

Then run zappa command.

$ zappa init
Create common environment here? [y/N] : y
Sqlite database stored path. [/tmp/oozappa/data.sqlite] :
Log files stored path. [/tmp/oozappa] :
Create directory or exit? "/tmp/oozappa" [y/N] : y
created common directory. db/log file path and flask secret key are in common/vars.py.

How to change settings

Open common/vars.py and change settings.

• OOZAPPA_DB

  sqlite’s data store path.

• OOZAPPA_LOG_BASEDIR

  Jobset execute log store directory path.

Create environment

Run zappa command with names option.

$ zappa create_environment --names construction deployment
2014-04-20 16:43:26,543 INFO create environment : construction
2014-04-20 16:43:26,544 INFO create environment : deployment

Then you can write fabfile normally and execute via oozappa.
