Tool for meeting these requirements:
-
Create a lean Docker Image from the Dockefile in this repo.
-
Tracking left over containers from a previous launch at ids.gob file so to stop them at next launch
-
To launch concurrently config.RequestedLiveContainers containers of the http://github.com/nethatix/echopathws http listener that echoes back the requested url path i.e., localhost:8770/1/2/3/ -> 1/2/3/.
-
Supporting a configurable number of live containers creation.
-
Supporting liveness both as an app and through few unit tests.
-
Consuming the Docker statistics streams for each live container. Optional persistence to an aggregated text file separate from the logs.
-
Displaying and aggregating all the logging input streams of the live containers similarly to the statistics streams.
-
Concurrently remove all live instances.
This is a statically configured command line application that is efficient and scalable.
This workflow/workflow_test.go->Test_Continuous_Logs_Http_Requests_100_Containers requires a large timeout to as the 30 seconds are not even sufficient to launch 100 instances. Υου may run it go test -run Test_Continuous_Logs_Http_Requests_100_Containers -timeout 100000s
within github.com/nethatix/tlex/workflow$
go test -run Test_Workflow_0_Containers
go test -run Test_Workflow_3_Containers_No_Stats
go test -run Test_Workflow_1_Containers
go test -run Test_Workflow_5_Containers
go test -run Test_Workflow_20_Containers -timeout 50s
go test -run Test_Continuous_Logs_Http_Requests_100_Containers -timeout 100000s
workflow/ // the unit tests root folder.
workflow/testdata/Dockerfile // the unit tests Dockerfile
workflow/testdata/logFile.log // the unit tests log file.
workflow/testdata/StatsLogFile.log // the stats unit tests file.
logger/logger_test.go // simple test case
dockerapi/ // has no test file but a few logic assert functions in .dockerapi/dockerapi.go employed at runtime

Preferably within $gopath\src
git clone https://github.com/nethatix/tlex
cd tlex
./install.sh (tested with windows bash) or install.cmd (windows)
Note the application builds and runs both on and off the gopath within the root tlex folder: These commands worked in both locations on/off gopath locations:
go build ./...
go vet
go build -race producing tlex or tlex.exe executables....
go run tlex
Dockerfile // (The employed docker image spec in root folder. )
logFile.log // is the application log file.
StatsLogFile.log // is the application stats file.
ids.gob // binary serialization of left over live containers.
