Reading the startup scripts does not elucidate how JVM options are
applied. Instead, the reader must consult the source for the JVM options
parser. This commit adds some transparency around this process so that
it easier to understand reading the startup scripts how the final JVM
options to start Elasticsearch are constructed.
* Set default ES_PATH_CONF for package scriptlets
Our packages use scriptlets to create or update the Elasticsearch
keystore as necessary when installing or upgrading an Elasticsearch
package. If these scriptlets don't work as expected, Elasticsearch may
try and fail to create or upgrade the keystore at startup time. This
will prevent Elasticsearch from starting up at all.
These scriptlets use the Elasticsearch keystore command-line tools. Like
most of our command-line tools, the keystore tools will by default get
their value for ES_PATH_CONF from a system configuration file:
/etc/sysconfig/elasticsearch for RPMs, /etc/default/elasticsearch for
debian packages. Previously, if the user removed ES_PATH_CONF from that
system configuration file (perhaps thinking that it is obsolete when
the same variables is also defined in the systemd unit file), the
keystore command-line tools would fail. Scriptlet errors do not seem to
cause the installation to fail, and for RPMs the error message is easy
to miss in command output.
This commit adds a line of bash to scriptlets that will set ES_PATH_CONF
to a default when ES_PATH_CONF is unset, rather than only when the
system configuration file is missing.
Back when the distribution launchers were compiled to target JDK 7, we
did not have access to the String#join method to space-delimit JVM
options. Since the launchers now target the same minimum JDK as
Elasticsearch itself, we now have access to this method and can replace
the use of spaceDelimitJvmOptions with String#join. This commit does
that.
This commit prepares the JvmOptionsParser to be more unit testable by
refactoring the class to have some input that it pulls from external
sources passed in as arguments. We do not change any functionality in
this commit, nor add any unit tests, we are only preparing the way.
Now that the FIPS 140 security provider is simply a test dependency
we don't need the thirdPartyAudit exceptions, but plugin-cli and
transport-netty4 do need jarHell disabled as they use the non fips
BouncyCastle security provider as a test dependency too.
This commit introduces the ability to override JVM options by adding
custom JVM options files to a jvm.options.d directory. This simplifies
administration of Elasticsearch by not requiring administrators to keep
the root jvm.options file in sync with changes that we make to the root
jvm.options file. Instead, they are not expected to modify this file but
instead supply their own in jvm.options.d. In Docker installations, this
means they can bind mount this directory in. In future versions of
Elasticsearch, we can consider removing the root jvm.options file
(instead, providing all options there as system JVM options).
* Reload secure settings with password (#43197)
If a password is not set, we assume an empty string to be
compatible with previous behavior.
Only allow the reload to be broadcast to other nodes if TLS is
enabled for the transport layer.
* Add passphrase support to elasticsearch-keystore (#38498)
This change adds support for keystore passphrases to all subcommands
of the elasticsearch-keystore cli tool and adds a subcommand for
changing the passphrase of an existing keystore.
The work to read the passphrase in Elasticsearch when
loading, which will be addressed in a different PR.
Subcommands of elasticsearch-keystore can handle (open and create)
passphrase protected keystores
When reading a keystore, a user is only prompted for a passphrase
only if the keystore is passphrase protected.
When creating a keystore, a user is allowed (default behavior) to create one with an
empty passphrase
Passphrase can be set to be empty when changing/setting it for an
existing keystore
Relates to: #32691
Supersedes: #37472
* Restore behavior for force parameter (#44847)
Turns out that the behavior of `-f` for the add and add-file sub
commands where it would also forcibly create the keystore if it
didn't exist, was by design - although undocumented.
This change restores that behavior auto-creating a keystore that
is not password protected if the force flag is used. The force
OptionSpec is moved to the BaseKeyStoreCommand as we will presumably
want to maintain the same behavior in any other command that takes
a force option.
* Handle pwd protected keystores in all CLI tools (#45289)
This change ensures that `elasticsearch-setup-passwords` and
`elasticsearch-saml-metadata` can handle a password protected
elasticsearch.keystore.
For setup passwords the user would be prompted to add the
elasticsearch keystore password upon running the tool. There is no
option to pass the password as a parameter as we assume the user is
present in order to enter the desired passwords for the built-in
users.
For saml-metadata, we prompt for the keystore password at all times
even though we'd only need to read something from the keystore when
there is a signing or encryption configuration.
* Modify docs for setup passwords and saml metadata cli (#45797)
Adds a sentence in the documentation of `elasticsearch-setup-passwords`
and `elasticsearch-saml-metadata` to describe that users would be
prompted for the keystore's password when running these CLI tools,
when the keystore is password protected.

* Elasticsearch keystore passphrase for startup scripts (#44775)
This commit allows a user to provide a keystore password on Elasticsearch
startup, but only prompts when the keystore exists and is encrypted.
The entrypoint in Java code is standard input. When the Bootstrap class is
checking for secure keystore settings, it checks whether or not the keystore
is encrypted. If so, we read one line from standard input and use this as the
password. For simplicity's sake, we allow a maximum passphrase length of 128
characters. (This is an arbitrary limit and could be increased or eliminated.
It is also enforced in the keystore tools, so that a user can't create a
password that's too long to enter at startup.)
In order to provide a password on standard input, we have to account for four
different ways of starting Elasticsearch: the bash startup script, the Windows
batch startup script, systemd startup, and docker startup. We use wrapper
scripts to reduce systemd and docker to the bash case: in both cases, a
wrapper script can read a passphrase from the filesystem and pass it to the
bash script.
In order to simplify testing the need for a passphrase, I have added a
has-passwd command to the keystore tool. This command can run silently, and
exit with status 0 when the keystore has a password. It exits with status 1 if
the keystore doesn't exist or exists and is unencrypted.
A good deal of the code-change in this commit has to do with refactoring
packaging tests to cleanly use the same tests for both the "archive" and the
"package" cases. This required not only moving tests around, but also adding
some convenience methods for an abstraction layer over distribution-specific
commands.
* Adjust docs for password protected keystore (#45054)
This commit adds relevant parts in the elasticsearch-keystore
sub-commands reference docs and in the reload secure settings API
doc.
* Fix failing Keystore Passphrase test for feature branch (#50154)
One problem with the passphrase-from-file tests, as written, is that
they would leave a SystemD environment variable set when they failed,
and this setting would cause elasticsearch startup to fail for other
tests as well. By using a try-finally, I hope that these tests will fail
more gracefully.
It appears that our Fedora and Ubuntu environments may be configured to
store journald information under /var rather than under /run, so that it
will persist between boots. Our destructive tests that read from the
journal need to account for this in order to avoid trying to limit the
output we check in tests.
* Run keystore management tests on docker distros (#50610)
* Add Docker handling to PackagingTestCase
Keystore tests need to be able to run in the Docker case. We can do this
by using a DockerShell instead of a plain Shell when Docker is running.
* Improve ES startup check for docker
Previously we were checking truncated output for the packaged JDK as
an indication that Elasticsearch had started. With new preliminary
password checks, we might get a false positive from ES keystore
commands, so we have to check specifically that the Elasticsearch
class from the Bootstrap package is what's running.
* Test password-protected keystore with Docker (#50803)
This commit adds two tests for the case where we mount a
password-protected keystore into a Docker container and provide a
password via a Docker environment variable.
We also fix a logging bug where we were logging the identifier for an
array of strings rather than the contents of that array.
* Add documentation for keystore startup prompting (#50821)
When a keystore is password-protected, Elasticsearch will prompt at
startup. This commit adds documentation for this prompt for the archive,
systemd, and Docker cases.

* Warn when unable to upgrade keystore on debian (#51011)
For Red Hat RPM upgrades, we warn if we can't upgrade the keystore. This
commit brings the same logic to the code for Debian packages. See the
posttrans file for gets executed for RPMs.
* Restore handling of string input
Adds tests that were mistakenly removed. One of these tests proved
we were not handling the the stdin (-x) option correctly when no
input was added. This commit restores the original approach of
reading stdin one char at a time until there is no more (-1, \r, \n)
instead of using readline() that might return null
* Apply spotless reformatting
* Use '--since' flag to get recent journal messages
When we get Elasticsearch logs from journald, we want to fetch only log
messages from the last run. There are two reasons for this. First, if
there are many logs, we might get a string that's too large for our
utility methods. Second, when we're looking for a specific message or
error, we almost certainly want to look only at messages from the last
execution.
Previously, we've been trying to do this by clearing out the physical
files under the journald process. But there seems to be some contention
over these directories: if journald writes a log file in between when
our deletion command deletes the file and when it deletes the log
directory, the deletion will fail.
It seems to me that we might be able to use journald's "--since" flag to
retrieve only log messages from the last run, and that this might be
less likely to fail due to race conditions in file deletion.
Unfortunately, it looks as if the "--since" flag has a granularity of
one-second. I've added a two-second sleep to make sure that there's a
sufficient gap between the test that will read from journald and the
test before it.

* Update version added in secure settings request

Today we are repeatedly checking if the current build is a snapshot
build or not by reading the system property build.snapshot. This commit
formalizes this by adding a build parameter to indicate whether or not
the current build is a snapshot build.
In 2bb31fe (v0.6.0!) we added DEBUG-level logging to the default config of
action loggers "for easier debugging". This change to the default config lives
on to this day. It does not obviously make debugging any easier any more, but
it does result in a good deal of log noise sometimes. This commit removes this
special case from the default config.
Closes#51198
This change changes the way to run our test suites in
JVMs configured in FIPS 140 approved mode. It does so by:
- Configuring any given runtime Java in FIPS mode with the bundled
policy and security properties files, setting the system
properties java.security.properties and java.security.policy
with the == operator that overrides the default JVM properties
and policy.
- When runtime java is 11 and higher, using BouncyCastle FIPS
Cryptographic provider and BCJSSE in FIPS mode. These are
used as testRuntime dependencies for unit
tests and internal clusters, and copied (relevant jars)
explicitly to the lib directory for testclusters used in REST tests
- When runtime java is 8, using BouncyCastle FIPS
Cryptographic provider and SunJSSE in FIPS mode.
Running the tests in FIPS 140 approved mode doesn't require an
additional configuration either in CI workers or locally and is
controlled by specifying -Dtests.fips.enabled=true

When installing multiple plugins at once, this commit changes the
behavior to report installed plugins as we go. In the case of failure,
we emit a message that we are rolling back any plugins that were
installed successfully, and also that they were successfully rolled
back. In the case a plugin is not successfully rolled back, we report
this clearly too, alerting the user that there might still be state on
disk they would have to clean up.
This commit allows the plugin installer to install multiple plugins in a
single invocation. The installation will be treated as a transaction, so
that all of the plugins are install successfully, or none of the plugins
are installed.
We renamed README.textile to README.asciidoc but a bunch of tests and
the package build itself still pointed at the old name. This switches
them the new name.
A previous commit taught Elasticsearch packages to respect ES_PATH_CONF
during installs. Missed in that commit was respecting ES_PATH_CONF on
upgrades. This commit does that. Additionally, while ES_PATH_CONF is not
currently used in pre-install, this commit adds respect to the preinst
script in case we do in the future.
Backport of #49612.
The current Docker entrypoint script picks up environment variables and
translates them into -E command line arguments. However, since any tool
executes via `docker exec` doesn't run the entrypoint, it results in
a poorer user experience.
Therefore, refactor the env var handling so that the -E options are
generated in `elasticsearch-env`. These have to be appended to any
existing command arguments, since some CLI tools have subcommands and
-E arguments must come after the subcommand.
Also extract the support for `_FILE` env vars into a separate script, so
that it can be called from more than once place (the behaviour is
idempotent).
Finally, add noop -E handling to CronEvalTool for parity, and support
`-E` in MultiCommand before subcommands.
We respect ES_PATH_CONF everywhere except package install. This commit
addresses this by respecting ES_PATH_CONF when installing the RPM/Debian
packages.
This commit tweaks the workaround introduced in #49211 to support
Gradle 6.0. In the workaround, we specifically override the address
the Gradle daemon binds to by passing the desired address via the
OPENSHIFT_IP environment variable. This works fine for builds using
Gradle 6.0, but for older Gradle versions this causes issues with
inter-daemon communication, specifically when we build BWC branches
not on Gradle 6.0. The fix here is to strip that environment variable
out when building the target BWC branch if that branch is on an
older Gradle version.
This is all temporary and will be removed when this bug fix is released
in Gradle 6.1.
Closes#50025
This upgrade required a few significant changes. Firstly, the build
scan plugin has been renamed, and changed to be a Settings plugin rather
than a project plugin so the declaration of this has moved to our
settings.gradle file. Second, we were using a rather old version of the
Nebula ospackage plugin for building deb and rpm packages, the migration
to the latest version required some updates to get things working as
expected as we had some workarounds in place that are no longer
applicable with the latest bug fixes.

The Apache Commons Daemon has some helpful features for Java
applications, like nice little next boxes for min heap, max heap, and
thread stack size. Our elasticsearch-service.bat script parses those
values out of the ES_JAVA_OPTS environment variable and provides them to
the Apache Commons Daemon invocation command in order to provide
sensible defaults. However, we failed to remove those values from the
ES_JAVA_OPTS environment variable, which meant they ended up in the
"Java Options" text box and would, from there, override whatever the
user put in the specific boxes for heap size or thread stack size.
This commit modifies the loop that parses ES_JAVA_OPTS to construct a
new enviroment variable containing only the values that aren't parsed
out for heap size or thread stack size, then uses that new enviroment
variable in the commons daemon invocation command.
JDK 14 has removed CMS. This commit restricts the support for CMS to JDK
8 through JDK 13, and defaults to G1 GC on JDK 14. We will revisit all
defaults in the future, but this ensures that we run with a
properly-configured garbage collector on JDK 14+.
This fixes a regression introduced in #42042. The logic here was
mistakenly inverted such that we only run these tests in a FIPS JVM
which is the opposite of what we intend.

Backport of #46599 and #47640. Add packaging tests for Docker.
* Introduce packaging tests for Docker (#46599)
Closes#37617. Add packaging tests for our Docker images, similar to what
we have for RPMs or Debian packages. This works by running a container and
probing it e.g. via `docker exec`. Test can also be run in Vagrant, by
exporting the Docker images to disk and loading them again in VMs. Docker
is installed via `Vagrantfile` in a selection of boxes.
* Only define Docker pkg tests if Docker is available (#47640)
Closes#47639, and unmutes tests that were muted in b958467.
The Docker packaging tests were being defined irrespective of whether
Docker was actually available in the current environment. Instead,
implement exclude lists so that in environments where Docker is not
available, no Docker packaging tests are defined. For CI hosts, the build
checks `.ci/dockerOnLinuxExclusions`. The Vagrant VMs can defined the
extension property `shouldTestDocker` property to opt-in to packaging
tests.
As part of this, define a seperate utility class for checking Docker,
and call that instead of defining checks in-line in BuildPlugin.groovy
This commit fixes the name of the UBI-based Docker image build contexts
to include "7" (to set us up for the future where we are likely to have
a ubi8-based image).
This commit registers the UBI-based Docker image projects in the build
so that their assemble tasks are executed when the top-level assemble
task is executed.
This commit introduces a consistent, and type-safe manner for handling
global build parameters through out our build logic. Primarily this
replaces the existing usages of extra properties with static accessors.
It also introduces and explicit API for initialization and mutation of
any such parameters, as well as better error handling for uninitialized
or eager access of parameter values.
Closes#42042
This commit simplifies the JDK copy specification in the archives build
so that it's a single line as opposed to an if/else with a repeated
body. This approach reduces the maintenance cost of this code.
