###Run DR simulators as docker container
1. Build docker container with ```docker build -t drsim_common:latest .```
2. Run the container ```docker-compose up```
3. For specific behavior of of the simulators, add arguments to the `command` entries in the `docker-compose.yml`.
For example `command: node dmaapDR.js --tc no_publish` . (No argument will assume '--tc normal'). Run `node dmaapDR.js --printtc`
and `node dmaapDR-redir.js --printtc` for details or see further below for the list of possible arg to the simulator
###Run DR simulators and all other simulators as one group
See the README in the 'simulator-group' dir.
###Run DR simulators from cmd line
1. install nodejs
2. install npm
Make sure that you run these commands in the application directory "dr-sim"
3. `npm install express`
4. `npm install argparse`
5. `node dmaapDR.js` #keep it in the foreground, see below for a list for arg to the simulator
6. `node dmaapDR_redir.js` #keep it in the foreground, see below for a list for arg to the simulator
###Arg to control the behavior of the simulators
**DR**
--tc tc_normal Normal case, query response based on published files. Publish respond with ok/redirect depending on if file is published or not.</br>
--tc tc_none_published Query respond 'ok'. Publish respond with redirect.</br>
--tc tc_all_published Query respond with filename. Publish respond with 'ok'.</br>
--tc tc_10p_no_response 10% % no response for query and publish. Otherwise normal case.</br>
--tc tc_10first_no_response 10 first queries and requests gives no response for query and publish. Otherwise normal case.</br>
--tc tc_100first_no_response 100 first queries and requests gives no response for query and publish. Otherwise normal case.</br>
--tc tc_all_delay_1s All responses delayed 1s (both query and publish).</br>
--tc tc_all_delay_10s All responses delayed 10s (both query and publish).</br>
--tc tc_10p_delay_10s 10% of responses delayed 10s, (both query and publish).</br>
--tc tc_10p_error_response 10% error response for query and publish. Otherwise normal case.</br>
--tc tc_10first_error_response 10 first queries and requests gives no response for query and publish. Otherwise normal case.</br>
--tc tc_100first_error_response 100 first queries and requests gives no response for query and publish. Otherwise normal case.</br>
**DR Redirect**
--tc_normal Normal case, all files publish and DR updated.</br>
--tc_no_publish Ok response but no files published.</br>
--tc_10p_no_response 10% % no response (file not published).</br>
--tc_10first_no_response 10 first requests give no response (files not published).</br>
--tc_100first_no_response 100 first requests give no response (files not published).</br>
--tc_all_delay_1s All responses delayed 1s, normal publish.</br>
--tc_all_delay_10s All responses delayed 10s, normal publish.</br>
--tc_10p_delay_10s 10% of responses delayed 10s, normal publish.</br>
--tc_10p_error_response 10% error response (file not published).</br>
--tc_10first_error_response 10 first requests give error response (file not published).</br>
--tc_100first_error_response 100 first requests give error responses (file not published).</br>
###Needed environment
DR
DRR_SIM_IP Set to host name of the DR Redirect simulator "drsim_redir" if running the simulators in a docker private network. Otherwise to "localhost"
DR_FEEDS A comma separated list of configured feednames and filetypes. Example "1:A,2:B:C" - Feed 1 for filenames beginning with A and feed2 for filenames beginning with B or C.
`DRR_SIM_IP` is needed for the redirected publish request to be redirected to the DR redirect server.
DR Redirect (DRR for short)
DR_SIM_IP Set to host name of the DR simulator "drsim" if running the simulators in a docker private network. Otherwise to "localhost"
DR_REDIR_FEEDS Same contentd as DR_FEEDS for DR.
The DR Redirect server send callback to DR server to update the list of successfully published files.
When running as container (using an ip address from the `dfc_net` docker network) the env shall be set to 'drsim'. . When running the servers from command line, set the env variable `DR_SIM_IP=localhost`
