Make sure you run make update if updating and not just git pull as you will often need the latest library submodule and possibly new upstream libraries.

Quick Start

Ready to run Docker image

All programs and their pre-compiled dependencies can be found ready to run on DockerHub.

List all programs:

docker run harisekhon/pytools

Run any given program:

docker run harisekhon/pytools <program> <args>

Automated Build from source

installs git, make, pulls the repo and build the dependencies:

curl -L https://git.io/python-bootstrap | sh

or manually:

git clone https://github.com/HariSekhon/DevOps-Python-tools pytools
cd pytools
make

To only install pip dependencies for a single script, you can just type make and the filename with a .pyc extension instead of .py:

make anonymize.pyc

Make sure to read Detailed Build Instructions further down for more information.

Some Hadoop tools with require Jython, see Jython for Hadoop Utils for details.

Usage

All programs come with a --help switch which includes a program description and the list of command line options.

Environment variables are supported for convenience and also to hide credentials from being exposed in the process list eg. $PASSWORD, $TRAVIS_TOKEN. These are indicated in the --help descriptions in brackets next to each option and often have more specific overrides with higher precedence eg. $AMBARI_HOST, $HBASE_HOST take priority over $HOST.

DevOps Python Tools - Inventory

  • Linux:
    • anonymize.py - anonymizes your configs / logs from files or stdin (for pasting to Apache Jira tickets or mailing lists)
      • anonymizations include these and more:
        • hostnames / domains / FQDNs
        • email addresses
        • IP + MAC addresses
        • AWS Access Keys, Secret Keys, ARNs, STS tokens
        • Kerberos principals
        • LDAP sensitive fields (eg. CN, DN, OU, UID, sAMAccountName, member, memberOf...)
        • Cisco & Juniper ScreenOS configurations passwords, shared keys and SNMP strings
      • anonymize_custom.conf - put regex of your Name/Company/Project/Database/Tables to anonymize to <custom>
      • placeholder tokens indicate what was stripped out (eg. <fqdn>, <password>, <custom>)
      • --ip-prefix leaves the last IP octect to aid in cluster debugging to still see differentiated nodes communicating with each other to compare configs and log communications
      • --hash-hostnames - hashes hostnames to look like Docker temporary container ID hostnames so that vendors support teams can differentiate hosts in clusters
      • anonymize_parallel.sh - splits files in to multiple parts and runs anonymize.py on each part in parallel before re-joining back in to a file of the same name with a .anonymized suffix. Preserves order of evaluation important for anonymization rules, as well as maintaining file content order. On servers this parallelization can result in a 30x speed up for large log files
    • find_duplicate_files.py - finds duplicate files in one or more directory trees via multiple methods including file basename, size, MD5 comparison of same sized files, or bespoke regex capture of partial file basename
    • find_active_server.py - finds fastest responding healthy server or active master in high availability deployments, useful for scripting against clustered technologies (eg. Elasticsearch, Hadoop, HBase, Cassandra etc). Multi-threaded for speed and highly configurable - socket, http, https, ping, url and/or regex content match. See further down for more details and sub-programs that simplify usage for many of the most common cluster technologies
    • welcome.py - cool spinning welcome message greeting your username and showing last login time and user to put in your shell's .profile (there is also a perl version in my DevOps Perl Tools repo)
  • Amazon Web Services:
    • aws_users_access_key_age.py - lists all users access keys, status, date of creation and age in days. Optionally filters for active keys and older than N days (for key rotation governance)
    • aws_users_unused_access_keys.py - lists users access keys that haven't been used in the last N days or that have never been used (these should generally be removed/disabled). Optionally filters for only active keys
    • aws_users_last_used.py - lists all users and their days since last use across both passwords and access keys. Optionally filters for users not used in the last N days to find old accounts to remove
    • aws_users_pw_last_used.py - lists all users and dates since their passwords were last used. Optionally filters for users with passwords not used in the last N days
  • Google Cloud Platform:
    • GCF - Google Cloud Functions written in Python:
    • gcp_service_account_credential_keys.py - lists all GCP service account credential keys for a given project with their age and expiry details, optionally filtering by non-expiring, already expired, or will expire within N days
  • Docker:
    • docker_registry_show_tags.py / dockerhub_show_tags.py / quay_show_tags.py - shows tags for docker repos in a docker registry or on DockerHub or Quay.io - Docker CLI doesn't support this yet but it's a very useful thing to be able to see live on the command line or use in shell scripts (use -q/--quiet to return only the tags for easy shell scripting). You can use this to pre-download all tags of a docker image before running tests across versions in a simple bash for loop, eg. docker_pull_all_tags.sh
    • dockerhub_search.py - search DockerHub with a configurable number of returned results (older official docker search was limited to only 25 results), using --verbose will also show you how many results were returned to the termainal and how many DockerHub has in total (use -q / --quiet to return only the image names for easy shell scripting). This can be used to download all of my DockerHub images in a simple bash for loop eg. docker_pull_all_images.sh and can be chained with dockerhub_show_tags.py to download all tagged versions for all docker images eg. docker_pull_all_images_all_tags.sh
    • dockerfiles_check_git*.py - check Git tags & branches align with the containing Dockerfile's ARG *_VERSION

    • yaml_to_json.py - YAML to JSON converter (because some APIs like GitLab CI Validation API require JSON)
    • see also validate_*.py further down for all these formats and more
  • Hadoop ecosystem & NoSQL:
    • Ambari:

      • ambari_blueprints.py - Blueprint cluster templating and deployment tool using Ambari API
        • list blueprints
        • fetch all blueprints or a specific blueprint to local json files
        • blueprint an existing cluster
        • create a new cluster using a blueprint

Detailed Build Instructions

Python VirtualEnv localized installs

The automated build will use 'sudo' to install required Python PyPI libraries to the system unless running as root or it detects being inside a VirtualEnv. If you want to install some of the common Python libraries using your OS packages instead of installing from PyPI then follow the Manual Build section below.

Manual Setup

Enter the pytools directory and run git submodule init and git submodule update to fetch my library repo:

git clone https://github.com/HariSekhon/DevOps-Python-tools pytools
cd pytools
git submodule init
git submodule update
sudo pip install -r requirements.txt

Offline Setup

Download the DevOps Python Tools and Pylib git repos as zip files:

https://github.com/HariSekhon/DevOps-Python-tools/archive/master.zip

https://github.com/HariSekhon/pylib/archive/master.zip

Unzip both and move Pylib to the pylib folder under DevOps Python Tools.

unzip devops-python-tools-master.zip
unzip pylib-master.zip

mv -v devops-python-tools-master pytools
mv -v pylib-master pylib
mv -vf pylib pytools/

Proceed to install PyPI modules for whichever programs you want to use using your usual procedure - usually an internal mirror or proxy server to PyPI, or rpms / debs (some libraries are packaged by Linux distributions).

All PyPI modules are listed in the requirements.txt and pylib/requirements.txt files.

Internal Mirror example (JFrog Artifactory or similar):

sudo pip install --index https://host.domain.com/api/pypi/repo/simple --trusted host.domain.com -r requirements.txt

Proxy example:

sudo pip install --proxy hari:mypassword@proxy-host:8080 -r requirements.txt
Mac OS X

The automated build also works on Mac OS X but you'll need to install Apple XCode (on recent Macs just typing git is enough to trigger Xcode install).

I also recommend you get HomeBrew to install other useful tools and libraries you may need like OpenSSL for development headers and tools such as wget (these are installed automatically if Homebrew is detected on Mac OS X):

bash-tools/setup/install_homebrew.sh
brew install openssl wget

If failing to build an OpenSSL lib dependency, just prefix the build command like so:

sudo OPENSSL_INCLUDE=/usr/local/opt/openssl/include OPENSSL_LIB=/usr/local/opt/openssl/lib ...

You may get errors trying to install to Python library paths even as root on newer versions of Mac, sometimes this is caused by pip 10 vs pip 9 and downgrading will work around it:

sudo pip install --upgrade pip==9.0.1
make
sudo pip install --upgrade pip
make

Jython for Hadoop Utils

The 3 Hadoop utility programs listed below require Jython (as well as Hadoop to be installed and correctly configured)

hdfs_time_block_reads.jy
hdfs_files_native_checksums.jy
hdfs_files_stats.jy

Run like so:

jython -J-cp $(hadoop classpath) hdfs_time_block_reads.jy --help

The -J-cp $(hadoop classpath) part dynamically inserts the current Hadoop java classpath required to use the Hadoop APIs.

See below for procedure to install Jython if you don't already have it.

Automated Jython Install

This will download and install jython to /opt/jython-2.7.0:

make jython
Manual Jython Install

Jython is a simple download and unpack and can be fetched from http://www.jython.org/downloads.html

Then add the Jython install bin directory to the $PATH or specify the full path to the jython binary, eg:

/opt/jython-2.7.0/bin/jython hdfs_time_block_reads.jy ...

Configuration for Strict Domain / FQDN validation

Strict validations include host/domain/FQDNs using TLDs which are populated from the official IANA list is done via my PyLib library submodule - see there for details on configuring this to permit custom TLDs like .local, .intranet, .vm, .cloud etc. (all already included in there because they're common across companies internal environments).

Python SSL certificate verification problems

If you end up with an error like:

./dockerhub_show_tags.py centos ubuntu
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:765)

It can be caused by an issue with the underlying Python + libraries due to changes in OpenSSL and certificates. One quick fix is to do the following:

sudo pip uninstall -y certifi &&
sudo pip install certifi==2015.04.28

Updating

Run make update. This will git pull and then git submodule update which is necessary to pick up corresponding library updates.

If you update often and want to just quickly git pull + submodule update but skip rebuilding all those dependencies each time then run make update-no-recompile (will miss new library dependencies - do full make update if you encounter issues).

Testing

Continuous Integration is run on this repo with tests for success and failure scenarios:

  • unit tests for the custom supporting python library
  • integration tests of the top level programs using the libraries for things like option parsing
  • functional tests for the top level programs using local test data and Docker containers

To trigger all tests run:

make test

which will start with the underlying libraries, then move on to top level integration tests and functional tests using docker containers if docker is available.

Contributions

Patches, improvements and even general feedback are welcome in the form of GitHub pull requests and issue tickets.
