# Why Fedora as base OS?
# * Fedora always has latest packages compared to CentOS.
# * Fedora does not need extra CentOS's EPEL repositories to install tools.
# **Note:** Being an OS image, Fedora runs as 'root'; and has '/' as it's default WORKDIR.
# This Dockerfile builds a container image for Atlassian Confluence, using
# atlassian-confluence-*.bin installer. The advantage of using the bin-installer is
# that it includes OracleJDK (now AdoptJRE). We do not have to depend on Oracle Java
# or manage it in our image. Big relief!
#
# Since this container image contains OracleJDK, we can not (re)distribute it
# as binary image, because of licensing issues. Though mentioning it in
# Dockerfile is ok.
#
# Note: Check build-instructions.md for building this image.
####################################### START - Environment variables #######################################
#
#
# CONFLUENCE_VERSION:
# ------------------
# The value for CONFLUENCE_VERSION should be a version number, which is part of the name of the confluence software bin/tarball/zip.
# ENV CONFLUENCE_VERSION 6.15.4
ENV CONFLUENCE_VERSION 7.1.0
# OS_USERNAME:
# -----------
# Confluence bin-installer automatically creates a 'confluence' user and a 'confluence' group. Just specify what it's name is.
ENV OS_USERNAME confluence
# OS_GROUPNAME:
# ------------
# Confluence bin-installer automatically creates a 'confluence' user and a 'confluence' group. Just specify what it's name is.
ENV OS_GROUPNAME confluence
# CONFLUENCE_HOME:
# ---------------
# * This needs persistent storage. This can be mounted on a OS directory mount-point.
# * It needs to be owned by the OS user 'confluence'; UID 1000 normally.
# * The exact value to set for this variable can be found out by running the bin-installer manually in a test container.
# Note: confluence.home needs to be set to the value of ${CONFLUENCE_HOME}
# in ${CONFLUENCE_INSTALL}/confluence/WEB-INF/classes/confluence-init.properties
# However, the bin-installer takes care of that automatically.
ENV CONFLUENCE_HOME /var/atlassian/application-data/confluence
# CONFLUENCE_INSTALL:
# ------------------
# * Persistent storage is not needed for these.
# * It is important to set this ENV var, because it is used in docker-entrypoint.sh
ENV CONFLUENCE_INSTALL /opt/atlassian/confluence
# TZ_FILE:
# -------
# This is the timezone file to use - by the container.
# Timezone files are normally found in /usr/share/zoneinfo/* .
# Set the path of the correct zone file you want to use for your container.
# Actual management of timezone is handled in the docker-entrypoint.sh,
# but it is important for it to specidied in image, or passed to the container.
# TimeZone is set in a non-so-straightforward way, for certain reason.
ENV TZ_FILE "/usr/share/zoneinfo/Europe/Oslo"
# JAVA_HOME:
# ---------
# It is optional (but good) to set JAVA_HOME.
# If you configure it, ensure that it is the path to the directory where you find the bin/java under it.
ENV JAVA_HOME /opt/atlassian/confluence/jre
# JAVA_OPTS:
# ---------
# Optional values you want to pass as JAVA_OPTS. You can pass Java memory parameters to this variable,
# but in newer versionso of Atlassian software, memory settings are done in CATALINA_OPTS.
# JAVA_OPTS "-Dsome.javaSetting=somevalue"
# ENV JAVA_OPTS "-Dhttp.nonProxyHosts=confluence.example.com"
# CATALINA settings:
# -----------------
# CATLINA_OPTS will be used by CONFLUENCE_INSTALL/bin/setenv.sh script .
# You can use this to setup internationalization options and also any Java memory settings.
# It is a good idea to use same value for -Xms and -Xmx to avoid frequence shrinking and expanding of Java memory.
# In the example below it is set to 1 GB. It should always be half (or less) of physical RAM of the server/node/pod/container.
ENV CATALINA_OPTS "-Dfile.encoding=UTF-8 -Xms1024m -Xmx1024m"
# ENABLE_CERT_IMPORT:
# ------------------
# Allow import of user defined (self-signed) certificates.
ENV ENABLE_CERT_IMPORT false
# SSL_CERTS_PATH:
# --------------
# If you have self signed certificates, you need to force Atlassian applications to trust those certs.
# This is very useful when different atlassian applications need to talk to each other over application links.
# This should be a path which you either volume-mount in docker or k8s.
ENV SSL_CERTS_PATH /var/atlassian/ssl
# DATACENTER_MODE:
# ----------------
# This needs to be set to true if you want to setup Confluence in a data-center mode, using multiple confluence instances.
# This can stay set as false, if you are running a standalone confluence (server) instance.
# This has no effect on the role of your confluence instance; which may be 'test' or 'production'.
ENV DATACENTER_MODE false
# CONFLUENCE_DATACENTER_SHARE:
# ---------------------------
# This is only used in DataCenter mode. It needs to be a shared location, which multiple confluence instances can write to.
# This location will most probably be an NFS share, and should exist on the file system.
# If it does not exist, then it will be created and chown to the confluence OS user.
# NB: FOr this to work, DATACENTER_MODE should be set to true.
# ENV CONFLUENCE_DATACENTER_SHARE /var/atlassian/confluence-datacenter
ENV CONFLUENCE_DATACENTER_SHARE /mnt/shared
# CLUSTER_PEER_IPS:
# ----------------
# Comma separated list of cluster peer IPs in datacenter mode.
# This is set automatically when run in Kuberenetes. No need to bother about it in Kubernetes.
# This 'needs' to be set if confluence is run on plain docker host in data-center mode.
# In that case, we need to pass it the IP addresses of the "peer" nodes - as ENV vars,
# and not the IP of this node itself.
# If you are running confluence as standalone, you don't need to bother about it.
# Reverse proxy specific variables:
# ================================
# X_PROXY_NAME:
# ------------
# The FQDN used by anyone accessing confluence from outside (i.e. The FQDN of the proxy server/ingress controller):
# ENV X_PROXY_NAME 'confluence.example.com'
# X_PROXY_PORT:
# ------------
# The public facing port, not the confluence container port
# ENV X_PROXY_PORT '443'
# X_PROXY_SCHEME:
# --------------
# The scheme used by the public facing proxy (normally https)
# ENV X_PROXY_SCHEME 'https'
# X_CONTEXT_PATH:
# --------------
# (formerly X_PATH)
# IMPORTANT: BREAKING CHANGE: This was formerly X_PATH. Please adjust your scripts/YAML/TOML files accordingly.
# The context path, if any. Best to leave disabled, or set to blank.
# ENV X_CONTEXT_PATH ''

# The internationlization commands shown below are added in the main RUN section further below. So no need to uncomment them here.
# Internaltionalization / i18n - Notes on OS settings (Fedora):
# ------------------------------------------------------------
# Note the file '/etc/sysconfig/i18n' does not exist by default.
# echo -e "LANG=\"en_US.UTF-8\" \n LC_ALL=\"en_US.UTF-8\"" > /etc/sysconfig/i18n

# ------------------------------------------------------------
# echo -e "LANG=\"en_US.UTF-8\" \n LC_ALL=\"en_US.UTF-8\"" > /etc/default/locale
# We need the following in the container image:
# * xmlstarlet to modify XML files.
# * findutils provide 'find' ,which is helpful in finding files, especially during development and trouble-shooting.
# * gunzip, hostname , ps are needed by installer.
# * 'which' is used by the installer to find the location of gunzip
# * iproute provides tools: ss/netstat for troubleshooting.
# * jq
# * graphviz was needed by a confluence plugin
# * change ownership of /etc/localtime to OS_USERNAME, so we can link to it in docker-entrypoint.sh
# * Download Confluence Software (bin-installer)
# * The bin-installer installs (bundled) Oracle Java automatically.
# Link: https://www.atlassian.com/software/confluence/downloads/binary/atlassian-confluence-${CONFLUENCE_VERSION}-x64.bin
# * The 'sync' below is silly but needed, so dockerhub can build the image correctly. Otherwise it occasionally fails.
# * After the installer is finished running, we fix some permissions, such as /opt/atlassian/*.
# ** This is needed because the installer runs as root and sets up those directories under root's ownership.
# The installer creats a user confluence.
# ** Later, we modify certain files inside the confluence_home, such as server.xml,
# using our docker-entrypoint.sh script, which runs as user confluence (UID 1000).
# After the installer is finished running, we fix ownership and permissions, such as CONFLUENCE_INSTALL and CONFLUENCE_HOME.
# The silly syncs are for Dockerhub to process this properly.
# The fonts are added because AdoptJDK/JRE does not contain fonts and Confluence complaints about it.
# Unattended installation:
# ------------------------
# * Reference: https://confluence.atlassian.com/confluence064/installing-confluence-on-linux-720411834.html
