With these examples, you create and run a minimal Apache httpd configuration for Zitadel with Docker Compose.
Whereas the guide focuses on the configuration for Apache httpd, you can inspect the settings for the Zitadel API, the Zitadel login and the database in the base Docker Compose file.

For running Apache httpd, you will extend the base Docker Compose file with the Apache httpd specific Docker Compose file.
specific docker-compose.yaml
Apache httpd terminates TLS and forwards the requests to Zitadel via unencrypted h2c. This example uses an unsafe self-signed certificate for Apache httpd. By executing the commands below, you will download the files necessary to run Zitadel behind Apache httpd with the following config:
httpd-external-tls.conf
# Download the configuration files.export ZITADEL_CONFIG_FILES=https://raw.githubusercontent.com/zitadel/zitadel/main/apps/docs/content/self-hosting/manage/reverseproxywget ${ZITADEL_CONFIG_FILES}/docker-compose.yaml -O docker-compose-base.yaml --quietwget ${ZITADEL_CONFIG_FILES}/httpd/docker-compose.yaml -O docker-compose-httpd.yaml --quietwget ${ZITADEL_CONFIG_FILES}/httpd/httpd-external-tls.conf -O httpd-external-tls.conf --quiet# Generate a self signed certificate and key.openssl req -x509 -batch -subj "/CN=127.0.0.1.sslip.io/O=Zitadel Demo" -nodes -newkey rsa:2048 -keyout ./selfsigned.key -out ./selfsigned.crt 2>/dev/null# Run the database, and Apache httpd.docker compose --file docker-compose-base.yaml --file docker-compose-httpd.yaml up --detach --wait db zitadel-init zitadel-external-tls login-external-tls proxy-external-tls# Test that gRPC and HTTP APIs work.

If the management console loads normally, you know that the HTTP and gRPC-Web and gRPC APIs are working correctly.
# You can now stop the database, the Zitadel API, the Zitadel login and Apache httpd.docker compose --file docker-compose-base.yaml --file docker-compose-httpd.yaml down
