These have been available via opt-in prior to v23 of Docker Engine with `DOCKER_BUILDKIT=1` ENV as a prefix to running `docker build`, however it's been requested to avoid the syntax.
No HereDoc (multi-line RUN with EOF marker) or `RUN --mount` available. This makes the `busybox` approach a hassle, so I've brought back the explicit creation of user and home dir.
Without the cache mounts, bring back `zypper clean`. It's not doing much as the `--cache-dir` is still set, but should reduce disk space for the `builder` layer. Local builds will be slower as a result when this layer is invalidated.
AFAIK, this also makes it tricky to use the `ZYPPER_OPTIONS`? So no longer DRY.
- Removing bulk of the noise from inline documentation.
- Packages bundled into single line like previous the Alpine version had.
- `CACHE_ZYPPER` is only used as an `ARG` in the `builder` stage.
- `zypper clean` wasn't able to clear anything from the install root, other than the `CACHE_ZYPPER` mount.
The additions from `adduser` reading `/etc` does not appear to apply if the directory already exists, and permissions (including SGID) are adjusted properly for the home dir.
This mean the excess backup copies in `/etc` are introduced again however.
BusyBox `adduser` was reading config from `/etc` that unnecessarily populates the home folder with various dot files.
Alternative approach is to create the user and home folder manually. This avoids some extra files like the `-` suffixed backup copies from `adduser`.
This addresses the bug #2330 by implementing a function which removes
control characters from the file output format html,csv,json at the
output.
In every instance called there's a check before whether the string
contains control chars, hoping it'll save a few milli seconds.
A tr function is used, omitting LF.
It doesn't filter the terminal output and the log file output.
see #2325.
"whenever HTTP/1.1 is used then the Accept header uses "text/*" as a MIME type.
This causes some minor issues with some of the checks we are doing"
As noted in #2304, the way that the '&' character is treated in the string part of a pattern substitution changed in Bash 5.2. As a result, the change that was made in #1481 to accommodate older versions of Bash (e.g., on MacOS) now causes testssl.sh to produce incorrect HTML output when run on Bash 5.2.
This commit encodes the '&' characters in the substitution strings in a way that produces correct results on multiple versions of Bash (3.2 on MacOS, 5.2 on Ubuntu 23.10, 5.0 on Ubuntu 20.04).
- If local folder ownership is for example `644` it will fail to handle the `COPY` regardless (while `744` would work).
- Creating the directory with higher permissions in the container does not appear to help.
Create `testssl` user (_and group_) with no password (`-D`) and default their shell to bash (`-s`):
- A group will implicitly be created with the same value as the user. `addgroup testssl` and `-G testssl` are not needed.
- Gecos data (`-g "testssl user"`) doesn't appear relevant to the project to be required? The default gecos value (`Linux User,,,`) should be fine.
