Bach docker-compose projects manager

Author: Manlio García info@manliogarcia.es

This project aim to ease the deployment of docker-compose project instances.

It does so by relying on docker image sources and docker-compose project templates.

These utilities expect certain file structure to function, and usually require root permissions to perform well.

Usage

Just clone the project and it's dependencies:

# git clone --recurse-submodules <git_clone_url> "/usr/local/lib/bach"

Now add “/usr/local/lib/bach/bin” to your path.

# export PATH="$PATH:/usr/local/lib/bach/bin"

Make this permanent adding the command to your bashrc.

# echo 'export PATH="$PATH:/usr/local/lib/bach/bin"' >>~/.bashrc

If you prefer, you may include the path system-wide instead.

# echo 'export PATH="$PATH:/usr/local/lib/bach/bin"' >>/etc/profile

You may also run install_autocompletion.sh to link bach autocompletion scripts:

# cd /usr/local/lib/bach && ./install_autocompletion.sh

Available commands

bach [-h] [ARGS]

This command allows to create, manage and destroy docker-compose projects who follow a strict convention in their structure. To learn how to use it, invoke it with the “-h” flag as the first argument.

All possible actions may be invoked this way to get extra information about them. I.E: you may call bach -h generate <project_name> to see a list of possible arguments and their default values.

Relevant files and folders

/etc/bach/config

This file contains a simple key-value dictionary, which holds the project config values. You may have config files in the following locations:

• /etc/bach/config
• /etc/bach.conf
• ~/.bach/config
• ~/.bach.conf

Their contents will take precedence over the default values in that order.

If for some reason all of these files are missing, the scripts will resort to default values.

Beware that some actions require having permissions over the files, specially the backup script. This is not always guaranteed to be the case, I.E: for volumes mounted in folders managed by docker.

/etc/bach/image_sources/

Configurable with "IMAGE_SOURCES_FOLDER" option.

The project expect this folder to contain the sources for docker images. They should be git projects, and the name of the folders shouls be the expected name for the image. E.G: “/etc/docker-compose/image_sources/odoo11-atlantux”

/etc/bach/compose_templates/

Configurable with "PROJECT_TEMPLATES_FOLDER" option.

The project will look here for templates of different docker-compose projects. They should be git projects, and the name of each folder should be the name of the service the project provides. E.G: “/etc/docker-compose/compose_projects/odoo11”

/srv/bach/<project_name>.d/<instance_name>/

Configurable with "INSTANCES_FOLDER" option.

Once created, a service instance should be stored in a structured way for other tools to be aware of them. This folder will probably also contain a “data” folder for the project persistent files and other instance files.

/srv/bach_backups/<project_name>.d/<instance_name>/

Configurable with "BACKUP_FOLDER" option.

Backups generated with this tool will be here by default. Once created, a service instance should be stored in a structured way for other tools to be aware of them. This folder will probably also contain a “data” folder for the project persistent files.
