You should add the libpng-dev package to your Dockerfile:
FROM php:5.6-apache
RUN docker-php-ext-install mysql mysqli
RUN apt-get update -y && apt-get install -y sendmail libpng-dev
RUN apt-get update &&
apt-get install -y
zlib1g-dev
RUN docker-php-ext-install mbstring
RUN docker-php-ext-install zip
RUN docker-php-ext-install gd
Then go to directory with Dockerfile and run:
docker build -t sitename .
It worked in my case:
Removing intermediate container f03522715567
Successfully built 9d69212196a2
Let me know if you get any errors.
EDIT:
You should see something like this:
REPOSITORY TAG IMAGE ID CREATED SIZE
sitename latest 9d69212196a2 19 minutes ago 414 MB
<none> <none> b6c69576a359 25 minutes ago 412.3 MB
EDIT2:
Just to double check everything:
Please run the docker build command this way:
docker build -t sitename:1.0 .
(adding :1.0 should not change anything, I added it just to have additional row in docker images output)
Then start the container:
docker run --name sitename_test -p 80:80 sitename:1.0
It should work just fine.
I assumed that apache is using standard port (80) - maybe you need to adjust that. If you have other services/containers listening on port 80 you can make your container listening on other port:
docker run --name sitename_test -p 8080:80 sitename:1.0
That will redirect the traffic from port 8080 to port 80 "inside" the container.
Normally you run container in the background. To do this add the -d option to the docker run command (but for testing purposes you can omit -d to see output in the console).
If you decide to run container in the background you can check logs using docker logs sitename_test. To follow the logs (and see updates in logs) use -f option:
docker logs -f sitename_test
Hope that helps.
