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`.
See #2328, original PR #2295 from @w4ntun .
Formally testssl.sh returned an error when it wasn't not possible to determine IP
addresses through DNS resolution, even if --proxy and --ip=proxy flags are set.
The main function always tried to determine IP addresses via DNS and exits with
a fatal error if it cannot do it. Although the client cannot get the IP, the
proxy could, so the SSL/TLS analysis is still possible.
This PR allows the analysis for an HTTP service via a proxy server and the DNS
traffic can be sent directly or through the proxy using the flag --ip=proxy.
ATTENTION: This may be a breaking change for those who don't have a local resolver.
They now have to add --ip=proxy.
In addition:
* help() was amended to add --ip=proxy (was only in the ~i/doc dir before)
* amending ~/doc dir to document it's better to add --nodns=min when there's
no local resolver
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).
