The only real way to know if it will work is to try. If you +find a container that doesn’t work and there is no known issue, please [file a +bug][bug] indicating the full command you used to run the image. You can view +open issues related to compatibility [here][issues]. + +If you're able to provide the [debug logs](../debugging/), the +problem likely to be fixed much faster. + +## What works? + +The following applications/images have been tested: + +* elasticsearch +* golang +* httpd +* java8 +* jenkins +* mariadb +* memcached +* mongo +* mysql +* nginx +* node +* php +* postgres +* prometheus +* python +* redis +* registry +* tomcat +* wordpress + +## Utilities + +Most common utilities work. Note that: + +* Some tools, such as `tcpdump` and old versions of `ping`, require explicitly + enabling raw sockets via the unsafe `--net-raw` runsc flag. +* Different Docker images can behave differently. For example, Alpine Linux and + Ubuntu have different `ip` binaries. + + Specific tools include: + +| Tool | Status | +| --- | --- | +| apt-get | Working | +| bundle | Working | +| cat | Working | +| curl | Working | +| dd | Working | +| df | Working | +| dig | Working | +| drill | Working | +| env | Working | +| find | Working | +| gdb | Working | +| gosu | Working | +| grep | Working (unless stdin is a pipe and stdout is /dev/null) | +| ifconfig | Works partially, like ip.
