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) | | start_project_cmd | The command to be used when starting projects is generally preferred to create a make file and make run| | start_project_suffix_cmd | This is the command to be executed after start_project_cmd. two commands are not piped together |

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
basket is running.
~$ service-runner.sh stop
product is not running
[*] basket is stopping
