+# container configuration override
+
+consult [Dockerfile](Dockerfile) or [docker-compose.yml](docker-compose.yml) - both are simple and fine enough.
+
+---
+
+mostly same as [simple static site](../basic/README.md) except container configuration file `j2cfg/override-compress-types.yml`.
+
+`j2cfg/override-compress-types.yml`:
+```yml
+compress_types: []
+
+---
+
+compress_types:
+- text/plain
+```
+
+this effectively disables response compression for all mime types except `text/plain`.
+
+---
+
+in order to enable (!) response compression specify environment variable `NGX_HTTP_CONFLOAD='gzip'` or `NGX_HTTP_MODULES='gzip brotli zstd'` (for gzip, brotli and zstd).
+
+---
+
+Test URI e.g. with `curl`:
+```sh
+curl -v --compressed http://127.0.0.1:8080/index.html
+
+curl -v --compressed http://127.0.0.1:8080/index.txt
+```
