我正在尝试为端点设置一个负载测试。到目前为止,这就是我所遵循的:
Dockerfile
FROM python:3.8
# Add the external tasks directory into /tasks
WORKDIR /src
ADD requirements.txt .
RUN pip install --no-cache-dir --upgrade locust==2.10.1
ADD run.sh .
ADD load_test.py .
ADD load_test.conf .
# Expose the required Locust ports
EXPOSE 5557 5558 8089
# Set script to be executable
RUN chmod 755 run.sh
# Start Locust using LOCUS_OPTS environment variable
CMD ["bash", "run.sh"]
# Modified from:
# https://github.com/scrollocks/locust-loadtesting/blob/master/locust/docker/Dockerfilerun.sh
#!/bin/bash
LOCUST="locust"
LOCUS_OPTS="--config=load_test.conf"
LOCUST_MODE=${LOCUST_MODE:-standalone}
if [[ "$LOCUST_MODE" = "master" ]]; then
LOCUS_OPTS="$LOCUS_OPTS --master"
elif [[ "$LOCUST_MODE" = "worker" ]]; then
LOCUS_OPTS="$LOCUS_OPTS --worker --master-host=$LOCUST_MASTER_HOST"
fi
echo "${LOCUST} ${LOCUS_OPTS}"
$LOCUST $LOCUS_OPTS
# Copied from
# https://github.com/scrollocks/locust-loadtesting/blob/master/locust/docker/locust/run.sh我是这样编写负载测试locust脚本的:
import json
from locust import HttpUser, constant, task
class CategorizationUser(HttpUser):
wait_time = constant(1)
@task
def predict(self):
payload = json.dumps(
{
"text": "Face and Body Paint washable Rubies Halloween item 91#385"
}
)
_ = self.client.post("/predict", data=payload)我是用一个配置来调用它的:
locustfile = load_test.py
headless = false
users = 1000
spawn-rate = 1
run-time = 5m
host = IP
html = locust_report.html因此,在构建和推送Docker映像并在GKE上创建k8s集群之后,我将部署它。这就是deployment.yaml的样子:

--port 80 \
--target-port 8089 \
--name locust-web集群和节点配置成功。但是当我访问locust-web的IP时,我得到的是:

关于如何解决这个问题,有什么建议吗?

可能是k8s设置的环境变量与蝗虫(特别是LOCUST_WEB_PORT)发生了冲突。更改您的设置,以便没有容器被命名为“蝗虫”。
