Configuration

Parameter	Description

log_folder	The full path of the folder where the log files of the projects will be created
dependency_map	The mapping list where you need to write the projects you can manage and their dependencies. The projects are separated by :
uncommitted_cmd	If there are changes committed in a project, if you are sure you want to update it, you should run the command to avoid a problem
uncommitted_cmd_msg	String to be printed after uncommitted_cmd
update_project_cmd	List of commands to use when updating project(s)

Example

Let's assume that you have product/basket/order services in an e-commerce project. If you need product service while developing the basket project, you can do this without the need for any virtualization. Let's start by creating the configuration.

For the above example, let's create the config.yaml as follows.

project_path: /Users/ree/go/src/github.com/ecommerce
log_folder: /tmp/ecommerce.log

dependency_map:
  - "product"
  - "basket:product"
  - "order:product:basket"

uncommitted_cmd: "git stash"
uncommitted_cmd_msg: "[*] existing changes are stashed"

update_project_cmd:
  - "echo '[*] git pull origin master'"
  - "git checkout master"
  - "git pull origin master"

start_project_cmd: "cd $project_path; make run"
start_project_suffix_cmd: "2>&1 | tee -a $LOG_FOLDER/$project.log"

Management Example

~$ service-runner.sh start basket
[*] product is running.
[*] basket is running.
~$ service-runner.sh show
product is running.
basket is running.
~$ service-runner.sh stop basket
[*] basket is stopping.
~$ service-runner.sh show
product is running.
~$ service-runner.sh stop product
[*] product is stopping
~$ service-runner.sh start basket depends_off
[*] basket is running.
~$ service-runner.sh show
