### ERPNext VM Builder
|
|
|
|
|
|
#### Steps to build a VM Image
|
|
|
|
* `python build.py` builds a new VM
|
|
|
|
|
|
#### Requirements
|
|
|
|
* Bench should be installed.
|
|
* Ansible should be installed
|
|
|
|
|
|
#### How it works
|
|
|
|
Apart from the above the rest is handled by bench:
|
|
|
|
* Install prerequisites if not already installed
|
|
- virtualbox
|
|
- packer
|
|
* Cleanup
|
|
- Clean the required directories
|
|
* Generate the erpnext_develop.json and the erpnext_production.json
|
|
- Figure out the latest ubuntu iso available, get it's link and the checksum and generate the json files
|
|
* Build the VM using packer
|
|
- Packer downloads the mentioned Ubuntu iso, boots a virtual machine and preceeds the preseed.cfg file into it in order to setup a clean Ubuntu OS
|
|
- Then packer uses ssh to enter the virtual machine to execute the required commands
|
|
- `scripts/debian_family/install_ansible.sh` sets up ansible on the vm.
|
|
- Depending on the VM being built, the `install_erpnext_develop.sh` or the `install_erpnext_production.sh` is executed
|
|
- `scripts/set_message.sh` sets welcome message (with update instructions) in the vm.
|
|
- `scripts/cleanup.sh` writes zero to all the free space in the disk, it shrinks the disk image
|
|
* Set the correct permissions for the built Vagrant and Virtual Appliance Images
|
|
* Cleanup
|
|
- Delete the generated files from the required directories
|
|
* restart nginx
|
|
|
|
The requirements for this to run are Packer and Virtualbox. imports the base image in a virtual machine and boots it. It runs the following
|
|
|
|
|
|
#### For a build server
|
|
|
|
Running the `build.py` script builds a vm and puts it in `~/public`. It also writes a `latest.json` file in `~/public` with filename of the latest build and its md5sum.
