Dockerコンテナ内でのviの挙動がおかしい

DockerでシンプルにApacheをインストールしたコンテナを作成しました。

DockerFile
1FROM centos
2
3LABEL title="TestApacheImage"\
4      version="1.0"\
5      description="test apache"
6
7RUN ["rpm", "--import", "/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7"]
8RUN ["yum", "-y", "install","httpd"]
9
10EXPOSE 80
11
12CMD ["/usr/sbin/httpd", "-D", "FOREGROUND"]

これを以下のコマンドで起動します。

#ビルド
docker image build -t apache -f DockerFile .

#run(viで開いたとき変な折り返しをしていたので環境変数いじってます)
docker container run -it -p 8080:80 -e COLUMNS=$COLUMNS -e LINES=$LINES -e TERM=$TERM apach

するとこのようなエラーが出たので

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message

ServerNameを編集するために、/etc/httpd/conf/httpd.conf をviで開いてみました。

httpd.conf
1#
2# This is the main Apache HTTP server configuration file.  It contains the
3# configuration directives that give the server its instructions.
4# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
5# In particular, see
6# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
7# for a discussion of each configuration directive.
8#
9# Do NOT simply read the instructions in here without understanding
10# what they do.  They're here only as hints or reminders.  If you are unsure
11# consult the online docs. You have been warned.
12#
13# Configuration and logfile names: If the filenames you specify for many
14# of the server's control files begin with "/" (or "drive:/" for Win32), the
15# server will use that explicit path.  If the filenames do *not* begin
16# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
17# with ServerRoot set to '/www' will be interpreted by the
18# server as '/www/log/access_log', where as '/log/access_log' will be
19# interpreted as '/log/access_log'.
20
21#
22# ServerRoot: The top of the directory tree under which the server's
23# configuration, error, and log files are kept.
24#
25# Do not add a slash at the end of the directory path.  If you point
26# ServerRoot at a non-local disk, be sure to specify a local disk on the
27# Mutex directive, if file-based mutexes are used.  If you wish to share the
28# same ServerRoot for multiple httpd daemons, you will need to change at
29# least PidFile.

31ServerRoot "/etc/httpd"

33#
34# Listen: Allows you to bind Apache to specific IP addresses and/or
35# ports, instead of the default. See also the <VirtualHost>
36# directive.
37#
38# Change this to Listen on specific IP addresses as shown below to
39# prevent Apache from glomming onto all bound IP addresses.
