Docker Image Preparation

Start an ubuntu v18.04 docker container

docker run -itd -p 8080:8080 ubuntu:bionic

TTY into Container

docker exec -it <containerID> /bin/bash

Prepare system for Oncall

apt update && apt -y upgrade &&
apt install -y git

Clone Oncall v1.2.3

cd /home &&
git clone --branch v1.2.3 https://github.com/linkedin/oncall.git &&
cd /home/oncall && git checkout -b v1.2.3-modification

Install oncall dependencies

apt install -y libssl-dev libxml2-dev libxslt1-dev libsasl2-dev
python3-dev libldap2-dev python3-pip python3-setuptools mysql-client mysql-server

Upgrade pip

python3 -m pip install --upgrade pip

Install pip pkg dependencies to avoid errors whe upgrading packages in next step

apt install -y libcairo2-dev libgirepository1.0-dev

Upgrade all outdated pip packages

python3 -m pip list --outdated --format=freeze | grep -v '^-e' | cut -d = -f 1 | xargs -n1 python3 -m pip install -U

⚠️ Received and Ignored the following errors:
ERROR: Cannot uninstall 'pygobject'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall

ERROR: Cannot uninstall 'pyxdg'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall

Install pip pkgs utilized by .github/workflows/create-release-and-publish.yml (may be unnecessary for making from source)

python3 -m pip install setuptools wheel twine

Install following to resolve PyYaml errors incurred when making onCall

apt install -y libyaml-dev libpython2.7-dev

Source Modifications

Commit history is presently available only in the early-notification/Docker/images/oncall:dev.tar.gz docker image. Until the original modifications are pushed to aoc-pathfinder, commit history may be viewed vis the following:

1. load the aforementioned image
2. run it as a container
3. exec into that container
4. git log --reflog

Pull down image, load, exec and see following commits in branch v1.2.3-modification

Commit History (v1.2.3-modification):

• d344b2c: Modified interpreters from python to python3
• 6277930: Converted all 'python' and 'pip install' calls to their python3 equivalents

Database Preparation

Set mysql_native_password as auth plugin so passwords may be utilized
Note: By default, mysql on ubuntu:bionic utilizes the 'auth_socket' auth plugin causing mysql+pymysql to fail to auth w/ a password; additional details here. Note: You may verify the current plugin by doing mysql> SELECT plugin from mysql.user where User="root";

service mysql start &&
mysql mysql -e "UPDATE user SET plugin='mysql_native_password' WHERE User='root';FLUSH PRIVILEGES;" &&
service mysql restart

Set mysql root password

mysql_secure_installation && service mysql restart Responses: [No, 1234, 1234, Yes. Yes, Yes, Yes]

Disable ONLY_FULL_GROUP_BY mysql mode as described here Note: these commands need to be run @ each mysql restart

mysql -u root -p1234 -e " SET SESSION sql_mode = sys.list_drop(@@SESSION.sql_mode, 'ONLY_FULL_GROUP_BY'); SET GLOBAL sql_mode = sys.list_drop(@@GLOBAL.sql_mode, 'ONLY_FULL_GROUP_BY'); CREATE DATABASE oncall; "

Load Schema

mysql -u root -p1234 < /home/oncall/db/schema.v0.sql

Load Mock Data

mysql -u root -p1234 -o oncall < /home/oncall/db/dummy_data.sql

Install Oncall

python3 setup.py develop &&
python3 -m pip install -e '.[dev]'

⚠️ 14-Aug: When testing this ReadMe using only python2, we had to run the following commands in the following order and separately (i.e. don't use &&):

python -m pip install -e '.[dev]'
python3 setup.py develop &&

Make Oncall
