Dockerized pdf2htmlEX
Summary
A super small image with pdf2htmlEX installed. The project icon is from cre.ativo mustard, HK from the Noun Project
NOTE: This image is marked EOL, and use is discouraged.
Usage
You can use this image locally with docker run, calling pdf2htmlEX:
docker run -v /media/:/media/ jrbeverly/pdf2htmlEX:privileged pdf2htmlEX report.pdf
Gitlab
You can setup a build job using .gitlab-ci.yml:
compile:
image: jrbeverly/pdf2htmlEX:baseimage
script:
- pdf2htmlEX report.pdf
artifacts:
paths:
- report.pdf
Components
Metadata Arguments
Metadata build arguments used with the Label Schema Convention.
| Variable | Value | Description |
|---|---|---|
| BUILD_DATE | see metadata.variable | The Date/Time the image was built. |
| VERSION | see metadata.variable | Release identifier for the contents of the image. |
| VCS_REF | see metadata.variable | Identifier for the version of the source code from which this image was built. |
Build Arguments
Build arguments used in the image.
| Variable | Value | Description |
|---|---|---|
| USER | see Makefile.options |
Sets the user to use when running the image. |
| DUID | see user.variable | The user id of the docker user. |
| DGID | see user.variable | The group id of the docker user’s group. |
Volumes
No volumes are exposed by the docker container. However, while running the image with limited permissions (baseimage), it is necessary to ensure that the docker user has permission to access mounted volumes. You will need to ensure that the docker user can read/write to the mounted volumes. (see User / Group Identifiers)
The working directory of the image is /media/.
Build Process
To build the docker image, use the included Makefile. It is recommended to use the makefile to ensure all build arguments are provided.
make VERSION=<version> build
You can view the build/README.md for more on using the Makefile to build the image.
Labels
The docker image follows the Label Schema Convention. Label Schema is a community project to provide a shared namespace for use by multiple tools, specifically org.label-schema. The values in the namespace can be accessed by the following command:
docker inspect -f '{{ index .Config.Labels "org.label-schema.<LABEL>" }}' jrbeverly/pdf2htmlEX
Label Extension
The label namespace org.doc-schema is an extension of org.label-schema. The namespace stores internal variables often used when interacting with the image. These variables will often be application versions or exposed internal variables. The values in the namespace can be accessed by the following command:
docker inspect -f '{{ index .Config.Labels "org.doc-schema.<LABEL>" }}' jrbeverly/pdf2htmlEX
User and Group Mapping
All processes within the baseimage docker container will be run as the docker user, a non-root user. The docker user is created on build with the user id DUID and a member of a group with group id DGID.
Any permissions on the host operating system (OS) associated with either the user (DUID) or group (DGID) will be associated with the docker user. The values of DUID and DGID are visible in the Build Arguments, and can be accessed by the commands:
docker inspect -f '{{ index .Config.Labels "org.doc-schema.user" }}' jrbeverly/pdf2htmlEX:baseimage
docker inspect -f '{{ index .Config.Labels "org.doc-schema.group" }}' jrbeverly/pdf2htmlEX:baseimage
The notation of the build variables is short form for docker user id (DUID) and docker group id (DGID).
