+# Logs Generator
+
+## Overview
+
+Logs generator is a tool to create predictable load on the logs delivery system.
+Is generates random lines with predictable format and predictable average length.
+Each line can be later uniquely identified to ensure logs delivery.
+
+## Usage
+
+Tool is parametrized with the total number of number that should be generated and the duration of
+the generation process. For example, if you want to create a throughput of 100 lines per second
+for a minute, you set total number of lines to 6000 and duration to 1 minute.
+
+Parameters are passed through environment variables. There are no defaults, you should always 
+set up container parameters. Total number of line is parametrized through env variable
+`LOGS_GENERATOR_LINES_TOTAL` and duration in go format is parametrized through env variable
+`LOGS_GENERATOR_DURATION`.
+
+Inside the container all log lines are written to the stdout.
+
+Each line is on average 100 bytes long and follows this pattern:
+
+```
+2000-12-31T12:59:59Z <id> <method> /api/v1/namespaces/<namespace>/endpoints/<random_string> <random_number>
+```
+
+Where `<id>` refers to the number from 0 to `total_lines - 1`, which is unique for each
+line in a given run of the container.
+
+## Image
+
+Image is located in the public repository of Google Container Registry under the name
+
+```
+gcr.io/google_containers/logs-generator:v0.1.1
+```
+
+## Examples
+
+```
+docker run -i \
+  -e "LOGS_GENERATOR_LINES_TOTAL=10" \
+  -e "LOGS_GENERATOR_DURATION=1s" \
+  gcr.io/google_containers/logs-generator:v0.1.1
+```
+
+```
+kubectl run logs-generator \
+  --generator=run-pod/v1 \
+  --image=gcr.io/google_containers/logs-generator:v0.1.1 \
+  --restart=Never \
+  --env "LOGS_GENERATOR_LINES_TOTAL=1000" \
+  --env "LOGS_GENERATOR_DURATION=1m"
+```
