gunicorn 配置：

gunicorn --bind "0.0.0.0:${SUPERSET_PORT}" --access-logfile '-' --error-logfile '-' --workers 1 --worker-class gthread --threads 8 --timeout 60 --limit-request-line 0 --limit-request-field_size 0 "${FLASK_APP}"

【问题讨论】：

您能否提供您在gunicorn 命令中引用的环境变量？

【解决方案1】：

我设法通过以下步骤来解决这个问题

# Deploy application
$ oc new-app --name superset apache/superset:latest -e SUPERSET_PORT=8088 -e SUPERSET_HOME=/data

# Create persistent volume, adjust "--claim-size" as needed
$ oc set volume deployment/superset --add -m /data --claim-name=superset-volume --read-only=false --claim-size="5Gi"

# Set up the Docker image, per https://hub.docker.com/r/apache/superset
$ oc exec deployment/superset -it -- superset fab create-admin \
                        --username admin \
                        --firstname Superset \
                        --lastname Admin \
                        --email admin@superset.com \
                        --password admin
$ oc exec deployment/superset -it -- superset db upgrade
$ oc exec deployment/superset -it -- superset load_examples
$ oc exec deployment/superset -it -- superset init

# Expose superset with an https route
$ oc create route edge --service=superset --insecure-policy=Redirect
