dda-devops-build
| team@social.meissa-gmbh.de | Website & Blog
dda-devops-build provide a environment to tie several DevOps tools together for easy interoperation. Supported tools are:
- aws with
- simple api-key auth
- mfa & assume-role auth
- hetzner with simple api-key auth
- terraform v0.11, v0.12 supporting
- local file backends
- s3 backends
- docker / dockerhub
- user / team credentials managed by gopass
- dda-pallet
Setup
Ensure that yout python3 version is at least Python 3.7!
sudo apt install python3-pip
pip3 install pip3 --upgrade
pip3 install pybuilder ddadevops deprecation
export PATH=$PATH:~/.local/bin
# in case of using terraform
pip3 install dda-python-terraform packaging
# in case of using AwsMixin
pip3 install boto3
# in case of using AwsMfaMixin
pip3 install boto3 mfa
Example Build
lets assume the following project structure
my-project
| -> my-module
| | -> build.py
| | -> some-terraform.tf
| -> an-other-module
| -> target (here will the build happen)
| | -> ...
from pybuilder.core import task, init
from ddadevops import *
name = 'my-project'
MODULE = 'my-module'
PROJECT_ROOT_PATH = '..'
class MyBuild(DevopsTerraformBuild):
pass
@init
def initialize(project):
project.build_depends_on('ddadevops>=0.5.0')
account_name = 'my-aws-account-name'
account_id = 'my-aws-account-id'
stage = 'my stage i.e. dev|test|prod'
additional_vars = {'var_to_use_insied_terraform': '...'}
additional_var_files = ['variable-' + account_name + '-' + stage + '.tfvars']
config = create_devops_terraform_build_config(stage, PROJECT_ROOT_PATH,
MODULE, additional_vars,
additional_tfvar_files=additional_var_files)
build = MyBuild(project, config)
build.initialize_build_dir()
@task
def plan(project):
build = get_devops_build(project)
build.plan()
@task
def apply(project):
build = get_devops_build(project)
build.apply()
@task
def destroy(project):
build = get_devops_build(project)
build.destroy()
@task
def tf_import(project):
build = get_devops_build(project)
build.tf_import('aws_resource.choosen_name', 'the_aws_id')
Feature aws-backend
Will use a file backend.dev.live.properties
where dev is the [account-name], live is the [stage].
the backend.dev.live.properties file content:
key = ".."
region = "the aws region"
profile = "the profile used for aws"
bucket = "the s3 bucket name"
kms_key_id = "the aws key id"
the build.py file content:
class MyBuild(AwsBackendPropertiesMixin, DevopsTerraformBuild):
pass
@init
def initialize(project):
project.build_depends_on('ddadevops>=1.0')
account_name = 'my-aws-account-name'
account_id = 'my-aws-account-id'
stage = 'my stage i.e. dev|test|prod'
additional_vars = {}
config = create_devops_terraform_build_config(stage, PROJECT_ROOT_PATH,
MODULE, additional_vars)
config = add_aws_backend_properties_mixin_config(config, account_name)
build = MyBuild(project, config)
build.initialize_build_dir()
Feature aws-mfa-assume-role
In order to use aws assume role in combination with the mfa-tool (pip install mfa
):
the build.py file content:
class MyBuild(class MyBuild(AwsMfaMixin, DevopsTerraformBuild):
pass
@init
def initialize(project):
project.build_depends_on('ddadevops>=1.0')
account_name = 'my-aws-account-name'
account_id = 'my-aws-account-id'
stage = 'my stage i.e. dev|test|prod'
additional_vars = {}
config = create_devops_terraform_build_config(stage, PROJECT_ROOT_PATH,
MODULE, additional_vars)
config = add_aws_backend_properties_mixin_config(config, account_name)
config = add_aws_mfa_mixin_config(config, account_id, 'eu-central-1',
mfa_role='my_developer_role',
mfa_account_prefix='company-',
mfa_login_account_suffix='users_are_defined_here')
build = MyBuild(project, config)
build.initialize_build_dir()
@task
def access(project):
build = get_devops_build(project)
build.get_mfa_session()
Feature DdaImageBuild
The docker build supports image building, tagging, testing and login to dockerhost. For bash based builds we support often used script-parts as predefined functions see install_functions.sh.
A full working example: doc/example/50_docker_module
Feature AwsRdsPgMixin
The AwsRdsPgMixin provides
- execute_pg_rds_sql - function will optionally resolve dns-c-names for trusted ssl-handshakes
- alter_db_user_password
- add_new_user
- deactivate_user
the build.py file content:
class MyBuild(..., AwsRdsPgMixin):
pass
@init
def initialize(project):
project.build_depends_on('ddadevops>=1.0')
...
config = add_aws_rds_pg_mixin_config(config,
stage + "-db.bcsimport.kauf." + account_name + ".breuni.de",
"kauf_bcsimport",
rds_resolve_dns=True,)
build = MyBuild(project, config)
build.initialize_build_dir()
@task
def rotate_credentials_in(project):
build = get_devops_build(project)
build.alter_db_user_password('/postgres/support')
build.alter_db_user_password('/postgres/superuser')
build.add_new_user('/postgres/superuser', '/postgres/app', 'pg_group_role')
@task
def rotate_credentials_out(project):
build = get_devops_build(project)
build.deactivate_user('/postgres/superuser', 'old_user_name')
