K6 load tests — Part VI

Containerization

https://www.freepik.com

A sample load test is added in the earlier sections of the series. GitHub repository - https://github.com/KavitaJadhav/k6_learning. Checkout commit ff1a928ee2d0d077165086c671b3b73377045a88.

Next, dockerize the test suit to run in the CI environment. Add Dockerfile to use golang:alpine image and install k6 inside it.

FROM golang:1.20-alpine as builder
WORKDIR /app
RUN go install go.k6.io/xk6/cmd/xk6@v0.9.2
RUN xk6 build


FROM alpine
WORKDIR /home/k6
COPY --from=builder /app /bin/

Next, build the image locally with the command:

docker build . -t k6_learning

Run a new container with the image built locally with the command:

docker run -i -v $(pwd):/home/k6 k6_learning \
k6 run v1/test.k6.io/test.js \
--config v1/test.k6.io/load-test-config.json \
--out json=summary/test.json \
-e ENVIRONMENT='uat'

Here, to increase the readability, the command is split across multiple lines. This is the print outcome along with test details and progress, which can be optimised with --quiet and --log-output options.

docker run -i -v $(pwd):/home/k6 k6_learning \
k6 run v1/test.k6.io/test.js \
--quiet --log-output=none \
--config v1/test.k6.io/load-test-config.json \
--out json=summary/test.json \
-e ENVIRONMENT='uat'

Next, integrate the SQL plugin to read from the database. Continued in Part VII.

Note: Subsequent parts of the series are available here.

Happy Testing!
