Standalone PHP application inside docker container with nginx unit

№ 9575 В разделе "Администрирование" от November 25th, 2018,

Yes, I know, complete documentation about containerization unitd with predefined config is absent, found examples just uploads config after container start, but not during build. Here’s my own Dockerfile with unitd, php, php-mysql module and uploading project’s configuration during image building.


FROM nginx/unit:1.7.1-php7.0

LABEL maintainer=""
LABEL description="More information here"

# install base dependencies

RUN    apt-get ${APT_FLAGS_COMMON} update && \
    apt-get ${APT_FLAGS_PERSISTENT} -y install apt-utils

RUN apt-get ${APT_FLAGS_PERSISTENT} -y install php7.0-gd php7.0-mysql php7.0-curl php7.0-mcrypt php7.0-xml php7.0-json php7.0-mbstring curl 

RUN    apt-get ${APT_FLAGS_COMMON} purge -y apt-utils && \
    apt-get ${APT_FLAGS_COMMON} autoremove -y && \
    apt-get ${APT_FLAGS_COMMON} clean && \
    rm -rf /var/lib/apt/lists/*

# do not autostart
RUN rm -f /etc/init.d/unit

COPY config.json /state/new_config.json


COPY index.php .

RUN mkdir preview
RUN chown -R www-data:www-data /www

# upload config to unitd and die
RUN unitd --state /state --pid /tmp/ && \
    curl -s -X PUT -d @/state/new_config.json \
         --unix-socket /run/control.unit.sock \
         http://localhost/config/ && \
    kill -9 $(cat /tmp/


# now container ready to start with predefined config
CMD ["unitd", "--no-daemon", "--state", "/state"]


    "listeners": {
        "*:80": {
            "application": "node"
    "applications": {
        "node": {
            "type": "php",
            "user": "www-data",
            "group": "www-data",
            "root": "/www",
            "index": "index.php"
